Grid Scroll Bug in Firefox 17.0.5

[TriggerThirst]

https://fiddle.sencha.com/#fiddle/rre

Make a grid inside of a viewport and fill it with enough data to scroll sufficiently. Scroll all the way down and click on a cell. The scroll will jump upwards and the cell you clicked will not be selected.

This happens in Ext 5.0, 5.1, and 6 but only in Firefox 17.0.5

I have not been able to get this to happen in anything else. Newer versions of Firefox and IE work fine. If the grid isnt in the viewport it also works fine.

Sorry if this is a duplicate I tried searching the forums and google and found nothing. I tried figuring it out but had no luck. Thanks.


Ext version tested:

• Ext 5.1.1 rev 451

Browser versions tested against:

• IE9
• FF17.0.5 (firebug 1.3.0.10 installed)
• FF31.2.0

DOCTYPE tested against:

• HTML 5

Description:

• Make a grid inside of a viewport and fill it with enough data to scroll sufficiently. Scroll all the way down and click on a cell. The scroll will jump upwards and the cell you clicked will not be selected.

Steps to reproduce the problem:

• Make a grid inside of a viewport
• fill it with enough data to scroll sufficiently
• Scroll all the way down and click on a cell

The result that was expected:

• Row clicked on should become selected

The result that occurs instead:

• Grid scrolls up and row is not selected

Sorry to bump but never got a reply of any kind. Is this something that could possibly have a workaround? Problem is that I'm developing an application internally and the version of firefox distributed currently is 17.0.5 and upgrading business wide is not a possibility. Thanks.
