I can confirm close situation in 10.4.2. My internal error is F2084 - AV0AC01996(0AB90000)-R00000460-0. MXX and GExpert installed.
No problem in 10.4.1.
Close and reopen project helps. Any attempts to compile or build a project end in killing bds.exe process.

I think, their intention was to make those controls always and prominently visible.

 

But then I wonder why they did not put those controls on the IDE's toolbar space. It would be more logical, IMO, and no IDE element can hide the toolbar space?

Compare VS 2019 Search (Ctrl+Q) on title bar. And Quick Launch in SQL Management Studio 18.
Nice and useful.
