Copying/Duplicating an effect with keyframes out of the boundaries of the destination leves ghost keyframes on it
I notice the remove keyframes after current keyframe (IIRC) is missing, and when an effect is copied to a different clip that is shorter than the origin clip, and there are keyframes present that are outside the length of the destination clip, these can't be removed, but affect the effect behaviour.
Use case that I found triggered the issue, keyframing an effect on a timeline track, and then copying it to a clip. I can't say this is an adequate workflow (wouldn't do it besides keeping some parameters that were useful), but maybe this could be better handled if the option to clean up the keyframes is removed.
EDIT: Just noticed the option wasn't removed, but it is hidden if the effects tab is too narrow! The overflow of these options isn't working correctly.
