The primary goal is to balance having the editor work as expected by developers (with Tab key affecting indentation) while also not impeding keyboard navigation.
* Tab indents, Shift+Tab unindents, but only when that indent would be valid. E.g. moving existing list items down or up one level.
* Indenting a selection always works.
* When an "invalid" indent is attempted, nothing happens and a toast is shown with a hint to press again to leave the editor.
* Attempting the same action again allows the textarea lose focus by allowing the browser's default key handler.
* Pressing Esc also loses focus immediately.
* No tab handling happens until the text editor has been interacted with (other than just having been focused).
* Changing indentation in block quotes adds or removes quote levels instead.
