'enter' should not defocus/blur the 'find' box; when finding within a page, hitting "enter" tends to replace the last match with a new line

I seem to hit this one a lot when I am navigating within a page using the keyboard.

Expected workflow:
* ctrl-f (for "find mode")
* type a common string
* hit enter, enter, enter (browsing through the search results)
* maybe type more to refine the search
* hit escape (to dismiss the 'find' mode/feature)

By my perception, this usually works fine until the *last* result (i.e. the focus changes when there is no further match). Although, when preparing this bug report, 'enter' always seemed to break the find focus.

I've found two workarounds (below), but it's hard to break the muscle memory that is so common for web-browsers (where I am usually performing a "find-on-page").

Workaround:
* use 'Alt-N' or 'Ctrl-G' to go to the next item, rather than enter.
