Thanks for the report. Can you please post a test case which reproduces this issue?

It is probably because of scrollable:true in my viewport.
I set it to false ,it's work ok.
There are left menus based on accordition on viewport's west.

Yes, if Ext.supports.Touch is true, then Viewport's afterLayout fails, because document.body is null.

afterLayout: function(layout) {
    if (Ext.supports.Touch) {        
        document.body.scrollTop = 0;
    }
    this.callParent([layout]);
}

Somehow it is only reproducible with a Viewport's "scrollable: true".

This is still present in Ext 6.0.2
