Cannot dismiss Find modalbar with keyboard after using Previous or Next buttons

[redmunds]

1. Ctrl-F to find some text in page
2. Click "Next" or "Previous" button to move to another instance
3. Press Enter or Esc

Result:
Nothing happens

Expected
Find modal bar is dismissed

Seems to be a focus issue -- click back in search field the keyboard works as expected.

Nominating for Sprint 32. @rajeshsegu Can you take this one?

[rajeshsegu]

@redmunds I can definitely take this. Thanks for finding the culprit. ;)

@rajeshsegu Looks like @SAplayer just posted a potential fix. Can you take a look at add comments in #5297?

[peterflynn]

Reviewed. Assigned to @redmunds as the core-team owner since it's nominated for Sprint 32.

[rajeshsegu]

@SAplayer I think the code needs a minor change, please fix it. Thanks.

@peterflynn @redmunds Otherwise, the fix looks pretty good.

[redmunds]

@rajeshsegu We decided not to take pull #5297, and you said that you would take this one over. We'd like to get this fix in Sprint 33 which ends 10/24. Let me know if you won't be able to work on it by then.

[redmunds]

@rajeshsegu FYI, I submitted a fix for this.
