Fix desync of td view camera and store state

[daniel-wer]

This bug led to a distortion of the 3d viewport when moving/zooming after maximizing it (could happen after minimizing it as well). The cause of the bug was a desynchronization of the 3d view camera internal state and its store state. The 3d view camera was adjusted when maximizing the 3d viewport without updating the store state. This led to distortion errors, afterwards.

I scanned the code but didn't find other occurrences where the 3d view camera is updated without updating the store state.

URL of deployed dev instance (used for testing):

• https://___.webknossos.xyz

Steps to test:

• Create some skeletons so that you see something in the 3d view
• Maximize the 3d view using .
• Then, without moving the mouse out of the 3d view or clicking, either zoom or move the 3d view -> No distortion should happen.
  • The repro can be a bit tricky. I would propose you to test this on master as well, to check whether the reproduction instructions work for you! For me the distortion doesn't always happen when zooming for some reason, but moving triggers it. If you cannot observe the distortion zoom a bit when not maximized and try again.

Issues:

• fixes When zoom is the first action, the aspect ratio looks odd. #5520
• fixes Distortion in 3D viewport #5448

Awesome! The fix makes sense to me 👍 I was on the verge of giving up reproducing this issue, but in the end the repro somehow worked all of a sudden. I don't really know what changed inbetween 🤷 On the new dev instance, I couldn't provoke this error at all (and no other error either), so, I think, this is safe to be merged 💯
