Steps to reproduce the problem:
1. Open any web page with vertical scroll bar.
2. Scroll down.
3. Remember the element (word of text, row of table, image), located at top of window's visible area (say, element X).
3. Change zoom level or change size of window.
Result: browser will change parameters of scroll bars.

What is the expected behavior?
After rezoom or resize the vertical position of element X must not be changed (element X must be located at top of visible area).

What went wrong?
After rezoom or resize the element X become unvisible (vertical position of element X relative of top of visible area is changed, and element X located above or below of visible area).

Did this work before? N/A
