[WinCairo][WK1] Can't paint a font after painting very large font For example, fast/text/letter-spacing-produces-nan-width.html contains a very large font. After load the test case, fast/text/simple-lines-float.html fails. > python3.exe ./Tools/Scripts/run-webkit-tests --wincairo --debug -1 --no-retry-failures fast/text/letter-spacing-produces-nan-width.html fast/text/simple-lines-float.html --iterations=2 -v > [1/4] fast/text/simple-lines-float.html passed > [2/4] fast/text/letter-spacing-produces-nan-width.html passed > [3/4] fast/text/simple-lines-float.html failed unexpectedly (reference mismatch maxDifference=255; totalPixels=1356) > [4/4] fast/text/letter-spacing-produces-nan-width.html passed The first test run of simple-lines-float.html passed, but failed in the second because it was after letter-spacing-produces-nan-width.html.
