1320890 - Dead keys working incorrectly in Mac OS X since FF ver. 50

Status: RESOLVED DUPLICATE of bug 1317906

(Core :: Widget: Cocoa, defect, P2)

Description

[sor.rge]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:50.0) Gecko/20100101 Firefox/50.0
Build ID: 20161123182536

Steps to reproduce:

In Mac OS X, when you type the first key in a dead key sequence, followed by a key that is not in any dead key sequence, you get two characters: the first dead key character and the second one that was pressed. Since Firefox v. 50 update, the second key press is ignored. Example: in the Norwegian keyboard layout, there is a dead key sequence [¨][e], which results in "ë". But if you type [¨][r], normally it will result in "¨r". In the new Firefox, it will result in "¨". It is very difficult to keep track of all "eaten" characters when typing text, which results in massive amount of typos.

Steps to reproduce:
Use Norwegian keyboard, press [¨] and then [r] in Firefox in any text input field (web page, address line, search etc.)


Actual results:

The text "¨" is entered.


Expected results:

The text "¨r" should have been entered.

I guess that this was already fixed in 51 Beta 3. Could you check it?

Confirmed this bug on Release Fx50.0.120161123182536 with macOS 10.12  
It works as expected on 51.0b4, 20161128075558 and Nightly 53.0a1, 20161129030222

note: for those using English (American) keyboards and changing input source to Norwegian,  "¨" is the "]" key.

Thank you very much. I guess that this is dup of bug 1317906, I'll check that in a couple of hours. (If this is a dup of bug 1317906, it'll be fixed in 50.1.0 to be released mid Dec.)

Okay, I confirmed that this is exactly a dup of bug 1317906.
