Plans for v12 support

[Thomas Löffler]

Hi there,

are there plans for a v12 support?
Would go deeper into that extension if there is no short-term plan or existing work which can be released soon.

I tried the changes in the pull request.
The collapse works fine, but it seams not to store the state. Because after a refresh all the contents are opened again. Also after saving a content.

Same for me, #6 works great, but it is not saved. Maybe this is not related to the PR because of #7
