afde8413c9cc455c9b63a26cc2bc56e4de28a5f4 <select> computes its selected option's style from outdated ancestor styles
not a security fix
confidence 0.1
signal score 7.27
Source/WebCore/html
Classified as not security-relevant.
Triage note: SelectFallbackButtonElement resolves the selected option's style via a fresh lineage walk (resolveOptionStyle) instead of computedStyleForEditability(), which would read stale styles mid style-resolution, to set direction/unicodeBidi. Style-resolution correctness, not security.
This commit was flagged by the signal scorer and reviewed by AI (not a human). It is listed only so the triage is auditable; there is no root-cause analysis because this is not a vulnerability fix.
