Operating system/version

Describe the bug

If the user's focus is on a floating window when invoking :Trouble then :TroubleClose or using auto_open then the cursor will be placed in a non-floating window, not the original floating location.

Steps To Reproduce

Generic:

1. Open file.
2. Open a floating window.
3. Open Trouble with either :Trouble or auto_open.
4. Cursor is in the file buffer.

Using the below repro:

1. nvim -u repro.lua
2. :Lazy update
3. :Trouble
4. :TroubleClose
5. Cursor is in the file buffer when it should be in the Lazy pop-up

Expected Behavior

Cursor will be placed back in the floating window in the correct position.
