VeraCrypt keyfile widget in GNOME Disks is unreachable with the keyboard
Originally created by @intrigeri on #15952 (Redmine)
Noticed while writing the automated tests. Apparently it’s not on the list of widgets one can select with “TAB”. Also, it has no description (in accerciser speak, probably translates to tooltip in GTK). Both combined make it very hard to interact with programmatically, and probably impossible with at least some kinds of universal access technologies.
