Message:

When kerning is enabled, word spacing is doubly accounted for in RenderText::computePreferredLogicalWidths
​https://bugs.webkit.org/show_bug.cgi?id=97146

Reviewed by Anders Carlsson.

Source/WebCore:

Test: fast/text/word-space-with-kerning.html

• rendering/RenderText.cpp:

(WebCore::RenderText::computePreferredLogicalWidths): When kerning is enabled, words are
measured with their trailing space, if there is one, then the width of a space is subtracted.
Changed that width, stored in the local variable wordTrailingSpaceWidth, to include the
word spacing, since it is included in the result of widthFromCache().

LayoutTests:

• fast/text/word-space-with-kerning-expected.html: Added.
