The patch landed in nightly and beta is affected.
:nical, is this bug important enough to require an uplift?
If not please set status_beta to wontfix.

Beta/Release Uplift Approval Request

• User impact if declined: The fill area of border image renders incorrectly with if the border vertical and horizontal border widths are different.
• Is this code covered by automated tests?: Yes
• Has the fix been verified in Nightly?: Yes
• Needs manual test from QE?: No
• If yes, steps to reproduce:
• List of other uplifts needed: None
• Risk to taking this patch: Low
• Why is the change risky/not risky? (and alternatives if risky): Reasonably simple patch, been on nightly for only two days.
  We could wait for a few more days before uplifting considering we are rather early in the beta cycle, just to be extra careful.
• String changes made/needed: None.
