Timeline keeps deselecting my square selection!
Most often it happens when I try to select a few keyframes using box selection from the bottom-right to the top-left. Especially event keyframes.

It rarely happens when I'm trying to move position, rotation or other keyframes, so I didn't record that - but when it starts happening, it keeps happening non-stop until it freaks me out x)
Restarting Spine doesn't help.
It happens more often with event keyframes.
Sometimes it starts when I try to move keyframes.
Actually, if you move multiple keyframes by dragging one of them, it works normally, but it's so annoying that I can't move box...
Also, if you move the selection box slowly, sometimes it works fine, but if you move it fast - it happens more frequently.
