Status: UNCONFIRMED

(Core :: Widget: Cocoa, defect, P3)

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.13; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20180103231032

Steps to reproduce:

Following terminology to keep things understandable: 
line = string with manually entered linebreak at the end
row = string which has been broken by DOM/CSS rendering

Type a long text without any manually entered linebreaks into a textarea. It must be long enough that it exceeds the width of the textarea. (Checkpoint: This should cause the line to be automatically broken into two (or more) rows.)

Now go to the beginning of the first line and hit CTRL + e.

FF 57.0.4 


Actual results:

When hitting CTRL + e the cursor will jump to the end of the first *row* of text.


Expected results:

CTRL + should jump to the end of the *line* ignoring any line-breaks that have been inserted as part of DOM/CSS rendering.

Chrome and Safari implement the expected behavior.
