Filter touch devices problem

on an ipad if i try filtering after scrolling down,
it doesn’t show the data.
it is as if the data appeared above the view-able area in the data table.
and i cant scroll up to see it

I have the same problem on any mobile device.
What I found out is, that this appears not when using a selectfilter which works nice.
But if you swipe down after each character you typed into the filter input in the header, the data appears.
And as you mentioned, this happens only when you scrolled down (maybe to bottom) before.
So this seems to be a kind of refresh bug.

I got it managed with the onBeforeFilter event:

onBeforeFilter: function (id, value, config) {
this.showItem(this.getFirstId());
}
