Thanks for the PR @vsgoulart! I'll add the highlights to the CHANGELOG.

Added forms changes via a3d5411.

I found one issue that we may want to address:

• We moved the popup editor toggle to the top of the line. This is something we may want to follow-up with in forms HTML editor, too:

  

  Generally speaking we don't hide contents and hence also don't scroll horizontally:

  

  But I recon that this field is somewhat special, as the HTML can be arbitrary (and huge). I understand why you decided to go this way. Let's align the toggle and we should be good.
