When I'm in the middle of a page with a lot of text
and I increase the text size, 
the text I'm reading moves out of the viewport.

This is very irritating. What I expect is that the text I'm reading stays in the viewport as good as possible when increasing text size. In this way I can keep reading.

Ofcourse this also happens when decreasing text size and resizing the window.

(This shouldn't be to hard to implement. For example:
When in- or decreasing text size or resizing the window,
the browser could always move the viewport to the uppermost word in the viewport.)
