If images are turned off in the browser, and you move the mouse pointer over the alternate text of a link that includes an image, the whole web page shakes just below the link and the mouse pointer changes shape very rapidly.

Reproducible: Always

Steps to Reproduce:
1. Go to "Tools -> Options -> Content".
2. Uncheck "Load Images Automatically".
3. Go to a page that demonstrates the issue.
4. Move the mouse pointer over a link that contains an image where alternate text is now shown. HTML code: <a href="..."><img src="..." alt="..."></img></a>

Actual Results:  
The page jumps up and down just below the link and the pointer changes between an arrow and hand shape very quickly which makes it very difficult to click on a link.

Expected Results:  
Pointer should change to a hand and stay that way while hovering over any link. Also the page should stay still (unless code on the page dynamically inserts, removes or resizes page elements).
