quick-format: post-accessibility update edits (#3753)

Browse source 
- Backspace from the very beginning of the input will delete the previous
bubble, as opposed to removing the input itself. If it makes it so that
two inputs are next to each other, they are merged.
- When a new input is created via a mouse click, and the current input
is empty, manually delete it right away. Waiting for the blur handler
to remove it makes it so that the bubbles shift back and forth for a moment
when a new input is added and the old input is not removed.
- Minor tweak to make sure that even if there's a 'br' before an input,
clicking before it will not make a new input and just refocus it.
