Pressing Delete with keyframes multi-selected removed keyframes from the wrong element. selectedKeyframes holds "<elementId>:<percentage>" keys and can outlive the element it was built on (a clip click, keyframe click, layers selection, or keyframe context menu changes the active element without clearing it, and a shift-selection can span elements). deleteSelectedKeyframes parsed only the percentage from each key and applied it to the active animation, ignoring which element each selected keyframe belonged to, so a stale selection deleted keyframes the user never targeted on the active element. Extract selectedKeyframePercentagesForElement, which keeps only the percentages whose key matches the active element id, and route the delete through it. The common case (all selected keyframes on the active element) is unchanged; stale cross-element keys are skipped instead of mis-applied.
