Bug report (I searched for similar issues and did not find one)
Current behavior
When expanding or collapsing a BladeView blade, dwm.exe crashes. The gif below only shows a portion of my screen, but when the recording blacks out, so does my entire desktop on both monitors.

Expected behavior
Expanding or collapsing the bladeview blade should not be able to crash DWM.
Minimal reproduction of the problem with instructions
Windows logs:
dxdiag:
This might be better filed as a DWM bug (it shouldn't be able to be crashed by a user app), but I don't know how to do that. The crash is triggered by the bladeview functionality directly, so I figure this is a fair starting point.
Other notes:
- Issue doesn't happen when the bladeview first renders - only when it animates from one state to another.
- I've tried restarting and the issue is still consistently reproducible
Minimal repro project: dwm_crash_bladeview_repro.zip * I've spoken with others and they were not able to reproduce on a Surface laptop.
