Bug 267352 – REGRESSION (268934@main?): [ Monterey ] imported/w3c/web-platform-tests/mathml/relations/css-styling/padding-border-margin/margin-003.html is a consistent failure

• Component: New Bugs
• Status: NEW

Description:
imported/w3c/web-platform-tests/mathml/relations/css-styling/padding-border-margin/margin-003.html

The first failure I saw on the dashboard was approximately 10/05/23 at 268941@main.  The regression range is https://commits.webkit.org/compare/268913@main...268941@main .  
There are no other test run reports on the dashboard between 268941@main and the last consistent passing at 268913@main.    Looking at the changes in the regression range, perhaps the changes to the RenderBlockFlow caused this (268934@main?)?
 
I have been unable to reproduce this at this time.
