Status: NEW

(Firefox :: Menus, defect, P5)

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0
Build ID: 20180516032328

Steps to reproduce:

Using desktop client,

1.  Open some page with a textbox/text area.  (e.g., https://bugzilla.mozilla.org/enter_bug.cgi#h=bugForm%7CFirefox)
2.  Click in a textbox and type some words
3.  Click on the menu button (3 bars in the upper right corner)
4a.  Type random letters.
4b.  Type left arrows or right arrows
4c.  Type up arrows or down arrows
4d.  Click on an earlier word in the text area


Actual results:

4a.  Random letters appear in the text area.  The menu remains open.
4b.  While user may type and delete letters, left arrow and right arrow do not allow the user to move back and forth as expected - wtf confusing behavior.
4c.  Up and down arrows do not affect the textarea; rather, the focus moves to the menu, after being able to type in the text area.
4d.  Rather than merely moving the cursor to the earlier word, as usual when one can edit text in a text area, the menu suddenly also closes.


Expected results:

4a.  Nothing, unless letters are bound the menu items.
4b,c.  Focus should be on menu, so arrows should move in menu; there should be no cursor visible
4d. Acceptable behavior if 4a is fixed!
