Message:

[MathML] Center of stretched curly bracket not always vertically centered
​https://bugs.webkit.org/show_bug.cgi?id=123715

Reviewed by Brent Fulgham.

Source/WebCore:

  • rendering/mathml/RenderMathMLOperator.cpp:

(WebCore::RenderMathMLOperator::fillWithExtensionGlyph): Update an assertion and
handle the case where two glyph pieces abut.
(WebCore::RenderMathMLOperator::paint): Do not offset the center glyph by y().

LayoutTests:

because MathML is changing rapidly, but we need it to test these changes.

  • mathml/presentation/mo-stretch.html: Update to show stretching characteristics

of all stretchable glyphs.
