Plugin doesn't work after 2 reloads. When you add plugin (Extras - Plugins - Add) it has path like plugins/trees/trees.js, but it doesnt work until reload. After reloading it works, but it has path ./plugins/trees/trees.js. After next reload you have path ./plugins/trees/trees.js and not working plugin.

To Reproduce Steps to reproduce the behavior:

1. Go to 'Extras - Plugins'
2. Add some plugin, check the path. It should be like 'plugins/...'
3. Close application
4. Open some already existed .drawio file from file explorer It doesn't reproduce, if you open file from File - open or File - Open recent
5. Check that plugin is working and it path has changed './plugins/...'
6. Reload application
7. Check that plugin doesn't work and it path has changed path './plugins/...'

Expected behavior After opening files from anywhere you have working plugins

Screenshots step 2 step 3 step 4

Hi, I can add some info on the cause:

• after installing a plugin, it is saved with full-path file://<full-path-to-js-file>
• In App.main, here the loading code assumes that it is a path starting with plugins or else it calls getPluginFile:

let pluginFile = await requestSync({
  action: 'getPluginFile',
  plugin: plugins[I]
  });

which in turn assumes it is a file-name only see here

so the issue is either when storing the plugin file in the settings as full-path or at processing it no considering that it is a full-path
