The postion of an embedded flash object changes very short but noticeable on
certain events, like window resizing or whenever several CSS style properties
change dynamically (e.g. on mouseover).

See the testcase for some examples.

Reproducible: Always
Steps to Reproduce:
1. Load the test case
2. Mouse-over the test links or resize the browser window
3. look at the top left corner of the page (scrolled entirely "up").

Actual Results:  
The flash object is flickerig in the top left hand corner. Thi sis most clearly
visible when resizing the browser window, less so with test cases 1 and 3 (and
absent with test case 2).

Expected Results:  
Display the flash object in its initial position

This bug likely depends on bug #238493 - there are many similar bugs depending
on that one which have to do with positioned divs as well.
