Juggl view crashes when reopening the vault or switching Obsidian workspaces.

[FrankRuis]

First of all, love the work you have done, great plugin :)

Whenever I reopen my vault or switch to a different Obsidian workspace where I previously had a Juggl view open the Juggl pane will crash and show the following message:

The error is reproducible in a new empty vault with only the Juggl plugin installed.

I also get the following stack trace in the console when switching workspaces:

Uncaught TypeError: Cannot read properties of undefined (reading 'on')
    at eval (plugin:juggl:15:329914)
    at t.e.tryTrigger (app.js:1:963725)

    at t.activeLeafEvents (app.js:1:1510414)
    at a (app.js:1:264427)

And two additional stack traces on vault startup:
