Working case:
I press Ctrl+L, type two letters, it shows "Loading", then the list of files. I press backspace, it shows only 1 remaining letter and a new list of files.
Failing case:
I press Ctrl+L, type two letters, it shows "Loading", then the list of files. I scroll the list down with the mouse, then press backspace. Nothing happens. Backspace starts working again only after I explicitly click at the input field.
