It looks like there is a potential overflow issue with x,y,width,height when defining rectangles (I did not try other shapes). If these values become too large, mousemove event handlers associated with that shape no longer fire.

Reproducible: Always

Steps to Reproduce:
1. define a large rectangle and its associated mousemove handler like so:
    <rect x="-32767" y="-32767" width="65535" height="65535"
          fill="green" pointer-events="fill" onmousemove="update(evt)"/>

2. save as an SVG file
3. open the SVG file
4. move the mouse over green shape

Actual Results:  
The "update" function never fires.

Expected Results:  
Expected "update" function to fire

If you decrease the values used in the rectangle above, the mousemove event will fire. For example, the following definition will work correctly:
    <rect x="-16384" y="-16384" width="32767" height="32767"
          fill="green" pointer-events="fill" onmousemove="update(evt)"/>

Attachment: Large rectangle does not fire mousemove events

The circles should respone to mousemove events. Uncomment the commented out <rect> and then comment out the following <rect>. Reopen the file and now the circles will respond to mousemove events.

I think this is probably a duplicate of bug 315383.
