5.1.1 Nightly: Mouse scroller on Firefox just move some millimeters the grid

[SebTardif]

See west panel of Fiddle: https://fiddle.sencha.com/#fiddle/el2

If you use a mouse scroller, usually between left and right button, in all other browser, we can move the grid vertical scroll enough to see new row, but on Firefox it's only moving the grid slightly.

Can also reproduce with official Sencha Example at: http://dev.sencha.com/ext/5.1.0/exam...hdrs-grid.html

Possible workaround (untill official patch will be released):

 Ext.define('Ext.overrides.scroll.Scroller', {
            override: 'Ext.scroll.Scroller',
            privates:{
                onPartnerScroll: function(partner, x, y) {
                    var axis = partner._partners[this.getId()].axis;
                    var position = this.getPosition();


                    if (axis) {
                        if (axis === 'x') {
                            if(x === position.x){
                                return;
                            }
                            y = null;
                        } else if (axis === 'y') {
                            if(y === position.y){
                                return;
                            }
                            x = null;
                        }
                    }


                    this.doScrollTo(x, y, null, true);
                }
            }
        });

Should this be conditional to detect Firefox?

It should work on all browsers (I tested it on Chrome, IE 11/10 and Firefox).

Possible workaround (untill official patch will be released):

I recently inherited support for an application that uses 4.1.1 where this issue persists. I attempted to use this 'workaround', but with no success.

There is no 'Ext.scroll.Scroller' defined. What version did you base this workaround for?

What version did you base this workaround for?

This thread is in the Ext 5 forum so it is safe to assume the workaround was only for Ext 5.
I have not seen an override posted for Ext 4.
