Keyframe search breaks on copied Morphs

[Paula-Kli]

Describe the bug
When cutting a morph via the right click menu the keyframes are still shown in the search prompt.

When pasting a morph they are added again. It is not completly clear to which keyframe the entries point at this point and pasting the respective morph again remains the references to only one keyframe

I cannot reproduce this.

When a morph is copied the search always finds the keyframes of the same morph, independently of which keyframe is selected.
