[BUG] Hint doesn't show when editing in queue

When editing a card in queue, the cloze hint text doesn't appear like it does when in the editor.

- Note: adding or editing the cloze hint still works though, we just can't see it after typing the hint and pressing enter. Fixing this would be nice to have a better visual feedback!

Reproduce editing a card in the queue and compare it with the editor, focusing on how cloze hint text is rendered after entering a hint and pressing Enter. Done means the hint is visibly shown in the queue while adding or editing continues to work.
