Might this be on top of the throbber?

No. The adapter off message will only be shown when the adapter is off, and in
that case, the system won't be able to scan for devices, so the throbber won't
be shown.

Ok, thanks. Could you add a comment here to that effect.

Done.

                                     2 * kAdapterOffHelpLinkPadding);

   // When there are no devices, the table contains a message saying there
   // are no devices, so the number of rows is always at least 1.
   return std::max(base::checked_cast<int>(chooser_controller_->NumOptions()),
                   1);
