FSE: when editing a navigation menu item's label, focus is lost each time you type a character

[nekohayo]

Description

Everytime I type a character in the editing field for menu labels, it defocuses the field, so I have to click to refocus it after every typed character.

Furthermore, this makes it impossible to type accented characters using dead keys (ex: typing ^ then e to create ê).

Step-by-step reproduction instructions

1. Insert a menu in the header template of your website and edit its contents using the sidebar on the right
2. Try to modify the label of an item in a submenu
