Enrica and I think that this is related to Chromium’s use of HarfBuzz on Mac. It’s also possible, though seems unlikely, that it’s related to sub-pixel layout.

If the tests are still failing, should we re-enable the optimization for harfbuzz-ng platforms? Maybe bashi has time to look into these failures.

This isn't a sub-pixel issue. The differences here are in the float values in the line box tree. My money is on HarfBuzz as well :) Thanks for helping us track this.

I think this is a good plan. To re-enable the optimization, all that needs to be done is remove the #if USE(HARFBUZZ_NG) and the remove the UNUSED_PARAMETER at the beginning of setLogicalWidthForTextRun
