Option to keep pickers open upon pressing Enter with an empty selection

[hb226]

Currently, when Enter is pressed in an empty picker (no items available or all items filtered out), the picker will close.

I find myself mistyping when quickly walking the file tree using the file explorer (skill issue), clearing the list of available items. If I then hit Enter, which I often do in the rhythm of traversing, the picker closes and I lose my place.

I have experienced this to a lesser degree on the other pickers as well.

I would like an option in the config (defaulting to current behavior) to keep the picker open upon pressing Enter with an empty selection so I can alter my query instead of re-walking the tree.

Would anybody else be interested in this?
I am willing to work on the implementation if there is interest.
