I'm skeptical of 292044@main being the regression point.

292044@main looks like the first revision on Sonoma where we ran this set. Certainly not a regression point.

[alan]

The 1px diff is caused by a difference in handing non-integral vertical values in ruby vs. regular inline content with emphasis.

[Bryan Medina]

It looks like the re-sync of these tests from upstream at https://commits.webkit.org/281435@main turned them from a constant pass to a constant failure.

[Vitor Roriz]

We have progressed the "under" ones at some point:
imported/w3c/web-platform-tests/css/css-text-decor/text-emphasis-position-under-left-001.xht
imported/w3c/web-platform-tests/css/css-text-decor/text-emphasis-position-under-right-001.xht

"over" ones are still failing for some platforms.
