not a security fix confidence 0.1 signal score 6.2 Source/WebCore/editing
Classified as not security-relevant.
Triage note: Switches AlternativeTextController to mainFrameViewRectForRange and drops the rootFrameID plumbing plus the async convertRectToMainFrameCoordinates in showCorrectionPanel; coordinate-space plumbing/refactor, no bug fixed.
