Improve settings editor dropdown layout

[roblourens]

Fork of #57447

The dropdown with details in the settings editor needs to account for the size of the details view when sizing and positioning itself, and when it needs to layout in an upwards direction, should (probably) have the details on top.

finally back online, FYI my normal schedule ranges from around two to usually around eleven or later. bit of an odd schedule, just so you know. pretty much working on VSC each day.

Is this the first thing you'd like me to work on for September? I assume no commits during endgame other than the critical bugs?

[roblourens]

We've created the release branch for 1.27 now, so commits to master are ok and will go into the September release.

good to know I was wondering if that's what you do.
if there's any issues for August you'd like me to work on this weekend I'm good with that, otherwise I'll start on this.

[roblourens]

I think this is the best thing to work on right now

If this looks good to you, I will clean and merge.

[roblourens]

I think that looks great! 😁

yeah, until it doesn't... ran into a very odd list focus issue, seems there several ways where the list gets focus as opposed to a list item. Result is a focus ring on the whole list. I got the detailed descriptions done but still working this. Just so you didn't think I disappeared... Once I bang my head some more I'll post something.
