'enter' is inconsistent in notebook find box

Testing #274956

Not sure if this is related to your work or totally separate?

- ctrl+F in a notebook to open find widget
- Type something to find
- If I press enter, it skips over every other match
- But if I press shift+enter, it goes backwards to each match correctly
