Triage nag: This Chrome OS bug has an owner but no component. Please add a component so that this can be tracked by the relevant team.

Update: Of the problematic click types listed above, (1) was already fixed and (2) is moot because we no long have a disabled button in the Settings Page so only (3) still requires a fix.

[CrOS MultiDevice] Stop link click from opening subpage in Settings Page

In the HEAD version, a click on the Settings UI 'learn more' link will
route to the subpage when there is a set host (i.e. when waiting for
connection/verification) in addition to the intended behavior of
opening the subpage. This CL just adds a check to the
settings-multidevice-page's click handler that returns before routing
if the click target was a link.
