Visualizer mapping messed up in current preview

[PathogenDavid]

Changing the visualizer doesn't take without restarting the visualizer target. Sometimes closing and reopening fixes.

Also Bonsai.Gui example can't be launched with --no-editor. (Maybe related?)

The crash noted here (but not the main issue) is potentially related to this: bonsai-rx/gui#35

I have not tracked down the exact commit, but I did notice this issue is coming from changes somewhere in the state watch PR #1975.

It doesn't show up in any of the other major 2.9 PRs yet is present in this PR branch alone.

This was due to incorrect detection of the currently active visualizer at runtime following the refactoring in #1870.

This turned out not to be related, but was a different issue traversing the workflow to set the layout notifications.

Both have been fixed in #2158, so will close this issue on merge. I was not able to reproduce any of this in the rebased workflow watch branch, so I am unsure again what was the exact source of issues in the preview. In the end we may decide to do a preview with the watch feature to see if anyone can reproduce this again.
