Eskil Abrahamsen Blomfeldt c9d991de1f Fix missing text when Harfbuzz fails to shape a substring
This amends fccd419dd6.

If Harfbuzz failed on one of the items in a string and returned
zero glyphs, then we would exit the shaping loop. The mentioned
change fixed a crash related to this when the ignored character
was the only character in the string, but it occurred in a
subitem of a longer string, then we would return and fail to
lay out the rest of the string.

This popped up recently because an update to Harfbuzz has caused
it to return zero glyphs when applying the Apple emoji font to
an isolated variant character (see bug report). When we matched
the symbol to the main font and only the variant character to
the emoji font, we would get in this situation, and end up
exiting the shaping early.

[ChangeLog][QtGui][Text] Fixed a regression which would
sometimes cause text to disappear if the string contained
an unmatched variation selector character.

Pick-to: 6.4
