Slight drift on touch screen #36

I don't know how to better describe this, so brace for it... Normally when I zoom in Edge, Chrome, any mobile browser, the two points that I touch with my fingers seem to always remain under my fingertips. E.g. if I want to zoom into the top part of this Github page, I can tap on the Github logo (top left) with my thumb and the nearby "Pull requests" button with my index finger and pinch out - as I pinch out, the logo will remain under my thumb and the button under my index finger. With this extension, however, the content drifts slightly towards the center. So at first it looks normal, but as I zoom in more and more, everything (and the logo&button) moves away from under my fingertips towards the center of the screen.

Now I think it just moves downwards instead of towards the center. Not really sure, but it's off.

I see what you’re getting at and it would be nice to fix it. I don’t currently have a touch device to test on but maybe @QWERTYUIOPYOZO would know more (as he added the touch screen feature)
