<table border=1 style="border-collapse: collapse"> will render

Notes:
The QTextDocument table model is much simpler than the HTML table model.
It basically only has <table> and <td> support. So the HTML parser is
forced to map markup and styling to the QTextDocument model which
is not without loss.
In other words: While QTextDocument -> HTML -> QTextDocument should
preserve the QTextDocument structure, HTML -> QTextDocument -> HTML
does not preserve the HTML DOM at all.
So for now the HTML importer and writer only support border styles on
the <td> and <th> nodes. In future updates, the HTML parser might be
enhanced to map <tr> and <table> CSS styles to the cells.

When calling QTextDocument::clearUndoRedoStacks() with UndoStack,
there were two bugs: The first was that we were retrieving
the item at "undoState" and deleting this. This is actually the
upper limit of the for loop. If the stack does not contain any
redos, then it would be == undoStack.size() and we would assert.
If there were redos, then we would delete the item at undoState
multiple times (actually undoState times).
In addition, when the loop exited, we first removed the dangling
pointers using remove() and then there was a weird resize() to
the new size minus the old undoState.
This would either assert because we tried to resize to a negative
number, or it would arbitrarily remove items from the stack.

QTextDocument::clearUndoRedoStacks(QTextDocument::UndoStack).

In 3ccdeb4b58, we removed the
specialized multi font engine on Windows, causing us to go
through the same code path when loading fallbacks as on
other platforms.
When combined with 97f73e9577,
this caused an error, because the code in
QFontEngineMulti::loadEngine() only overrode the families
list, but not the singular family in the request. In the
QRawFont test, this would cause the requested fallback font
to correctly have "MS Shell Dlg2" as the only font in the
families list, but the request.family would still be
"QtBidiTestFont", the name of the main font. The singular family
in the request was preferred by the windows font database when
creating the LOGFONT. We would therefore load the latter for
the fallback as well and since it still does not support the
characters in question, we would continue searching.

When eliding text we would check for the existence of the ellipsis
character and fall back to using the dot if it was not available.
However, when font merging was in use, we would also use ellipsis
from a fallback font if available. This could cause the metrics
of the text to increase if the fallback font had larger metrics,
and the result was that text could shift when elided.
It is better to prefer the dot from the current font than to use
the ellipsis from a fallback, so we only use the ellipsis if
it is in the main font.

Fenced code blocks have the advantages of being easier to write by hand,
and having an "info string" following the opening fence, which is commonly
used to declare the language.
Also, the HTML parser now recognizes tags of the form
<pre class="language-foo">
which is one convention for declaring the programming language
(as opposed to human language, for which the lang attribute would be used):

When reading a document like
# heading
- list item
and then re-writing it, it turned into
# heading
- # list item
because QTextCursor::insertList() simply calls QTextCursor::insertBlock(), thus
inheriting block format from the previous block, without an opportunity to
explicitly define the block format. So be more consistent: use
QTextMarkdownImporter::insertBlock() for blocks inside list items too. Now it
fully defines blockFormat first, then inserts the block, and then adds it to
the current list only when the "paragraph" is actually the list item's text
(but not when it's a continuation paragraph). Also, be prepared for applying
and removing block markers to arbitrary blocks, just in case (they might be
useful for block quotes, for example).

Since the comma character was originally used as a separator, we
need to extend QFont to have setFamilies() so that we can avoid
joining the family strings together. This enables us to see the
family name as a single string and for multiple family names,
we have families().
Subsequently, this has added functions to QTextCharFormat to
account for multiple font families too. So it is now possible to
set a single one directly with setFontFamily() and multiple ones
with setFontFamilies().
This also bumps up the datastream version to 19 as QFont now
streams the families list as well.

However, when executing the "if (d->priv)" condition in setters,
this will access the non-const operator->() of QSharedDataPointer
and detach the QTextCursorPrivate, and in the copy constructor of
this class, there was an unprotected call into priv->addCursor().
In theory, we could cast all the checks for d->priv to avoid
