Dragging clip to perfectly good space on timeline fails.
This one is a little difficult to describe, so I have attached a short video.
In words, when dragging a clip forward on the timeline, and there is another clip in the way, that clip stops it dead, even though there is enough space for the clip in the space ahead of the blocking clip. In the past, the clip would just "pop" into the space.
Should you drag the clip around the blocking clip, and into the space, it pops back to it's original place upon mouse release.
The workaround here is to first drag the clip to another track on the timeline, and then back in. This extra step is a small annoyance that detracts from the polish of Kdenlive.
