Use the same initial check for the accessible object type that we use
when connecting the signal, in case we try to disconnect signals on
different widgets. Additionally, check before accessing data that might
have already been removed.
Fixes: #3403
The accessibility bus might not be available, and if it isn't the case,
it means something has failed at a level where the user can't do much
about it. There's no need to emit a critical warning.
We depend on GObject, which already depends on GLib; on older versions
of Meson, this ends up trying to depend on the system copy of GLib,
instead of the sub-project copy, in case the version of GLib we have
installed is too old.
To avoid bleeding edge deprecations we use GLIB_VERSION_MIN_REQUIRED and
GLIB_VERSION_MAX_ALLOWED. Since we depend on GLib 2.66, we cannot use
API introduced in 2.67, even when conditionally compiled.
- Reorder declaration blocks for code legibility.
- Don't lighten text color on :hover and :selected for better contrast.
- Add missing :focus-visible:focus-within styling to non-:selected row.
- Don't set the sidebar padding twice.
- Add padding to the assistant sidebar directly, as it doesn't have
.navigation-sidebar internally.
- Set missing margin to the sidebar separator.

If an active grab gets undone on button press (e.g. closing a menu), we
will receive a button release on the new target even though it didn't handle
the button press, and disable ::active state.
This causes warnings when handling the button release, as it tries to undo
::active state that is not really there.
In order to fix this, check that the pointer focus actually had an implicit
grab at the time of receiving the button release, before trying to unset
the ::active state.
If the accessible object is hidden, we can skip the emission of the
AddAccessible and RemoveAccessible signals on the cache, as those
objects won't be visible in the accessibility tree.
Simplify getting the accessible role when checking if an accessible
implementation should present itself; this avoids going through
GtkAccessible twice to get the same data.
The GtkAtSpiContext is responsible for removing itself from the root,
which will remove itself from the cache. Any code path that leads to the
GtkAtSpiContext instance being collected passes through the
unrealization phase, which will also unregister the context from the
accessibility bus and from the cache.
- use the old Industrial style menuitems to make the design feel purposeful
- adjust corners to have compatible border-radii of child elements
- include sidebars and navigation sidebars to look consistent
(plus the assistant sidebar)

Since GTK4, the functions that used the GtkPackType enumeration,
`gtk_box_pack_{start,end}`, were replaced by `gtk_box_{append,prepend}`,
hence this enumeration isn't used anymore by any function within the
GtkBox type, and the child packing properties were also removed for GTK4.
So this commit adapts the documentation accordingly.
For readonly properties, we show the serialized value
in a label. If we don't take precautions, this can cause
our window to grow extremely wide, and break things.
So, ellipsize things at a reasonable size.
