Adding a menu custom link during autocompletion does not add the full text in firefox

[Nessworthy]

Tested on Firefox 30.0

In Appearance => Menus, creating a menu and adding custom links does not save the full link text under the condition that you have selected an auto complete value and hit the enter key.

Presumably, the auto complete value should be inserted, then the field should be saved with that value.

Entering:

Submitting/Saving (via enter key):

Result:

This applies to both the link URL and the link name. Didn't add the link URL screenshots to save screen space.

I think I've seen this in Chrome before too.

Issue seems to be due to a Firefox known bug regarding the timing / order of FF's autocomplete internal workings and the keypress event.

The bug is discussed from the perspective of the browser in BugZilla ticket 286933 at ​https://bugzilla.mozilla.org/show_bug.cgi?id=286933

First pass in an attempt to fix firefox's autocomplete bug affecting adding custom menu links. The patch was based on the answer of the linked StackOverflow question: ​http://stackoverflow.com/questions/2303955/i-have-a-problem-with-keydown-event-and-autocomplete-in-firebox-on-mac

I figure that this should be discussed before considering any patches, but the workaround is simple enough to prepare just in case.

It's clear that this issue is still in discussion in BugZilla, and whether to go ahead and add the autocompleted text into the field before user scripts are triggered is only one possible option discussed.

This is an issue that has been in talks for 9 years; I don't think any headway is going to be made on it any time soon.
