Issues when entering dynamics by typing

Issue type

UX/Interaction bug (incorrect behaviour)

Description with steps to reproduce

Two related issues.

1. Open the dynamics popup by selecting a note and typing Ctrl+D
2. Click the left or right arrows in the popup to move to view a different subset of dynamics
3. Attempt to type a dynamic into the text box; nothing happens, because focus has shifted to the popup itself.

This works perfectly as intended as long as you have not clicked in the popup.

Secondly:

1. Open the dynamics popup by selecting a note and typing Ctrl+D
2. Type a dynamic (f, whatever) and press Enter. This creates a line break. Evidently you have to press Esc or click elsewhere to exit edit mode.

Enter should (arguably) do the same as Esc. I'm not saying it should be impossible to have a line break in a dynamics object, but it's an unlikely requirement and could be done in text editing mode. If the user presses Enter, gets the line break and realises they need to press Esc to get out, this has still left them with a dynamics object with a line break at the end (see video) which while not likely to be disastrous, is not ideal either.
