No commit on that repo since 2021, so apparently still blocked.

Now the context menu doesn't even work on the desktop anymore.

Update: works again after cache deletion.

Update 2: it breaks after resetting the view.
However only in the version in the gh-pages branch that is build by the github action.
npm run dev and npm run build followed by npm run preview do not show this problem.

After checking out a fresh copy, it breaks also with "npm run preview".
