I made some test and you made an amazing job !

I see an issue that I was working on on my side, the form collections.
For example if you choose an Image collection element, the form is not loaded :

Form collections seems to be managed with Live component now, and not in JQuery like before.

Another issue with Image element, the selected image is not displayed

Also in the form

Yes, I saw these problems.
I also have 2 others problems, first one is markdown to html, the filter doesn't work and the other one is, I inject jQuery manually with a script balise...
But I'm still working on this upgrade !
