Something changed in either 2025-06-30 or 2025-09-09 client update. It no longer allows the unusable state, but keyboard accessibility is still terrible.
No focus indicator.
Esc doesn't work, unless you Tab first (which invisibly moves focus to the path text label) then Esc closes the modal.
Also try Tab 3 times then Space—you can "activate" the inactive Create Backup button and make it flash blue repeatedly :)
