@Jarko Yes the id field in plugin.json is not used, you need to change the name field in package.json
...and that was the issue indeed! Thank you! 💃
A problem is spotted in Firefox 52.7.4 32bit (Windows): user cannot use the post's dropdown menu:
On click the page is immediately scrolled to the top of the page.
Of course, I understand that asking to fix the issue for a browser of 2018 is too much, but I just want to be sure that that's because of the old browser and not the forum bug.
@aleksei if you want to make sure then try using a newer browser and see if it works
Works fine in latest firefox.
