Working well for me locally in the Project Wizard and the Data Explorer filters 🙌

This changed worked for the console info panel! There was some scenarios for small widths that caused the popup to get cut off but I think that has to do with the anchor point for the popup getting cut off and not scaling. Overall a much better improvement than what we had before.

I did have a comment and a couple questions but overall looks great!

This PR dealt almost exclusively with vertical layout and vertical scrolling, which is where the major problems of #3061 were to be found. I still have to deal with horizontal layout issues. I was not able to do this work in this PR because it was time-boxed for this milestone.
