[OOPP] Right-clicking on some flash videos causes CPU usage to spike; browser hangs

STR:
1) Right-click on flash content like the wind speed indicator at http://weather.weatherbug.com/NY/New%20York-weather.html?nav_section=1&zcode=z6286

CPU usage spikes and browser hangs for a little while and sometimes have to kill m-r.exe process.  If you close the browser the m-r.exe process doesn't die.

At one point I did get a "A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete.
Script: chrome://global/content/bindings/general.xml:0""

You can reproduce on the above page but it is a lot easier to reproduce on windowed plugins.

When right clicking on flash, the context menu stays freezed even if the browser is minimized.

Sometimes the 100% CPU goes away with click on the menu.
If I switch to another window the CPU goes back to normal and the flash menu disappears.

I tested with wmode transparent and opaque and without wmode.

With transparent and opaque the flash sometimes crashes.

I dont get any freeze if there is no wmode on the flash, so this problem is caused by wmode.

Here is a url with wmode transparent, opaque and without wmode.

BTW the transparent wmode is not working, filled bug 552111

reopening, I miss duped this to the wrong bug and can't find the context menu crashing bug now.

Should be fixed by the patch in bug 545149.
