Yeah. I've been able to reproduce this on the master branch.
To confirm what was said above, the lock seems to happen as a response to
clicking on the other document tab while this animation file is open.
Seems likely to be a thread locking / data race issue, so I'm not sure how
useful this'll be, but I have a backtrace:
