1137926 - Input Event listener fires twice or incorrectly preventing field Input

Status: RESOLVED INACTIVE

(Firefox for Android Graveyard :: Keyboards and IME, defect)

Description

[B Garza]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.115 Safari/537.36

Steps to reproduce:

Adding an event listener for "input" on a INPUT field seems to cause the event to fire twice or cause some DOM elements to be reset. This behavior is observed on mobile Android 4.4.4 - Firefox 35, but not on other versions of Android. 


Actual results:

After adding a new event listener to a textbox that registers the listener to handle other behavior such as reading a different input field on the form, the field with focus will not allow input. As each character is input, the preceding character is overwritten. 


Expected results:

On other versions of Firefox, the textbox with the event listener can be filled in with no issues.

Just to check, does that particular install of Firefox have any extensions?

No extensions- this was a new install from the Play Store on a Samsung Galaxy S5 running Android 4.4.4

I think so. I can take it since I've been looking at IME.
