Lots of frames apparently breaking GameMaker

[gm-bug-reporter]

Description

I imported a lot of frames of animation and wanted to move some around. It appareantly ended up breaking the entire preview window, so when I tried to delete all of the frames as a result, it ended in a fatal crash.

I should note that when editing the sprite in the sprite ediotr, the frames show up as normal. Seems to be a bug with the timeline window in general.

Steps To Reproduce

• Import 40+ frames to a sprite
• Select multiple frames, move them around to a different poition of the timeline and place them there
