Probably a regression from bug 621117

Could reproduce in Safari but couldn't in Chrome.

This suggests this is at least partly a bug in Silverlight, or possibly in the web page itself.  Have you tried reporting this issue to ImageSurf?

By the way, bug 621117 fixed a whole class of problems, and this appears to be the first bug filed against it since it landed (a year and a half ago).  If this is the only "regression" from the patch for bug 621117, I don't think it's reasonable to back out bug 621117 -- even if we can't fix (or work around) this bug.

No, we should not back out bug 621117. As a lower-priority item we should consider whether we can force the mouse cursor back to normal when the mouse leaves a plugin element.
