commit cfa633916c1086583e98c8b8611c154c639f3ff1

MD User Manager: fix excessively triggering user pod selections.

Currently, in the (md_)user_pod_row.js code, there's key-down listeners
that are bound directly on the document element, so its catching arrow/enter
key events from the create-user or supervised-user interface, and triggering
user-pod selections even while #user-pods-page is visually hidden.

This CL stops any keydown event propagation from the interfaces mentioned
above, as a solution with minimal code-change. A follow-up is recommended
to examine whether or not it's necessary to bind listeners for user-pod
selections on the entire document.
