The bug doesn't affect layout in a reliable way. Please rerun inside the layout test framework." I am happy to do PR and fix it but would appreciate input of others. Thanks! 1911780 1 ahmad.saleem792 2022-11-11 03:47:33 -0800 I think the problem with this merge is that the test cases use internal APIs which are not present in Webkit. I tried it here: https://github.com/WebKit/WebKit/pull/6368 FAIL internals.updateStyleAndReturnAffectedElementCount() should be 1. Threw exception TypeError: internals.updateStyleAndReturnAffectedElementCount is not a function. (In 'internals.updateStyleAndReturnAffectedElementCount()', 'internals.updateStyleAndReturnAffectedElementCount' is undefined) FAIL internals.needsLayoutCount() should be 0. Threw exception TypeError: internals.needsLayoutCount is not a function. (In 'internals.needsLayoutCount()', 'internals.needsLayoutCount' is undefined) ____ Any solution would be appreciated. Thanks! 1911909 2 ahmad.saleem792 2022-11-11 15:06:51 -0800 Close my PR with following comment: "I have to close this bug because Webkit does not support "-webkit-columns: auto " properly and also don't have related Internals Webkit Testing Framework API to land this as it is. I have added first parsing bug as "See Also" while also explained the internal testing framework thing on the bug for future reference. Closing this now." If we can land this without test case then it is good to go.
