An area that is hidden in the display via a clip path inihibits the mouse events of surrounding objects. It appears to apply to all objects that fall under the original path, the part that is "clipped" away.

Reproducible: Always

Steps to Reproduce:
1. Create an object that reacts to mouse events
2. Create a second object that covers the first one.
3. Apply a clippath to the second object so that the first object is visible.
4. First object does not receive mouse events

Actual Results:  
Currently, under the scenario described above, the first object does not receive mouse events

Expected Results:  
The first object should receive mouse events

Hopefully, you can fix this before the release. We are counting on Mozilla for deploying our product, but this is a show stopper for our project since I do not think there is a work around.

This is quite large, but readily shows the problem

Attachment: Simpler test case

Same problem, much simpler SVG

This problem appears to happens only when both shape are reusing the same clip-path, and that one of the shape is moved via a transform attribute. If you take the simple test case, duplicate the clip path and assign the duplicate to one of the object, then the behaviour is what would be expected.

Attachment: Compare using different clip paths to using the same one

This attachment provides a comparison between reusing a clip path and using different ones. Two equivalent cases are shown: one that reuses a clip path via a transform and a second, which uses two clip paths to obtain the same effect.

I have tried the last testcase and am able to observe the problem on Firefox 1.5 RC1 for OSX.
