In fringe cases snapping of Keyframes does not work as expected

[linusha]

In some small amount of scenarios (can only be reproduced by trial-and-error) the snapping of Keyframes will not work. This is due to the implementation of the snapping and how the position of Keyframes is converted into positions of TimelineKeyframes in timeline/index.js.

The solution would be to either purely rely on the model or on the view for snapping. This is however hard and the problem is only apparent in a very small amount of cases.

Also happens for sequences in overview timeline, happend when dragging tree and day background. The snapping indicator for tree sequence to night background was not shown

But it is also only some (edge) cases?
