Megathread: Sometimes, focus moves weirdly

[zadjii-msft]

I'm just making a megathread for all the issues we've got so far, because there's a bunch, and I'm getting the feeling there needs to be some other comprehensive solution.

• Clicking the current tab to raise the window should focus the text area Clicking the current tab to raise the window should focus the text area #3609
• ESC from the Tab ContextMenu should return focus to the Terminal ESC from the Tab ContextMenu should return focus to the Terminal #5750
• Launching "Find" from Command Palette doesn't focus the search box Launching "Find" from Command Palette doesn't focus the search box #6662
  • Unsure when exactly this was fixed
• Focus bug 1
  • open command palette
  • press shift+tab
  • your focus is now in the underlying terminal
    • As of 1.7, now the focus is gone from the world?
      • As of at least 1.9, this takes focus to the command list.
• Focus bug 2
  • open command palette
  • type in asdf, or anything that causes no results to match.
  • press tab
  • your focus is now gone from this world
  • Unsure when exactly this was fixed
• The "Rename tab" action removes focus from terminal The "Rename tab" action removes focus from terminal  #9160 (PR: Teach tab to focus terminal after rename #9162)

if we don't manually yeet the focus back into the active control, then pressing esc to close the command palette actually ends up with focus in the first Tab, similar to in #5750.

I do have one open PR: "When the tab receives focus, immediately move focus to the active control #6290", but I have no idea if that's the right solution. It doesn't feel like it is.
