I was able to bisect a regression point using the flakiness dashboard. This test reproduced at 266202@main, but it did not reproduce at 265998@main. Changes at 266000@main appear to be directly related to this error, and is likely what caused the failure.

I was able to reproduce this bug on macOS Ventura running the test as follows:

run-webkit-tests --ios-simulator imported/blink/fast/text/international/inline-block-with-mixed-direction-words.html

Comment 4 Ben Schwartz 2023-07-26 09:59:08 PDT

I was also able to bisect the regression point through local testing. I can confirm that 266000@main is the regression point.
