Reverse arrows weirdly scaling when Ctrl+A to select all objects while the song's playing in editor

Bug description

See in the linked video:
【osu!】一些不该出现在lazer编辑器里的东西反而出现了

An icon, shaped like "( << )", flickers when using Ctrl+A to select all and scroll back the timeline. It behave in this loop: start from a very large size, and quickly shrinks to minimum. Its position would change when you re-Ctrl+A. It would flicker for some time and then stop.

the linked video was recorded by Steam Overlay, since I couldn't reproduce this issue; and I guss it not that easily reproducable.

I was checking if the objects are distributed well in the playfield and this happened. I don't know if other mappers had experienced the same issue, but let's assume they did.

other bugs in the video:

• song muted
• Follow circle not updated (now fixed)

Looks like the reverse icon on the end of sliders doing its animation thing. Another edge case of animation weirdness in the editor no doubt.

This happened again, but this time I wasn't selecting any object. I did Ctrl+A before that though.
