Actually keyboard traps are a WCAG violation and should never happen
Snippet: 2.1.2 No Keyboard Trap: If keyboard focus can be moved to a component of the page using a

then focus can be moved away from that component using only a keyboard interface, and, if it requires more than unmodified arrow or tab keys or other standard
exit methods, the user is advised of the method for moving focus away. (Level A)
