Description Fujii Hironori 2023-03-07 17:06:38 PST

The 'length' argument of U16_FWD_1 in TextUtil::breakWord is wrong

If I applied bug#215318 patch, fast/text/midword-break-before-surrogate-pair.html is failing as assertion failure for WinCairo debug, and it is failing as infinite loop for WinCairo release.

> ASSERTION FAILED: middle >= left && middle < right
> C:\home\webkit\gc\Source\WebCore\layout/formattingContexts/inline/text/TextUtil.cpp(276) : WebCore::Layout::TextUtil::breakWord::<lambda_1>::operator ()
