setting the value of wmode in <embed> and <object> tags

Let the TinyMCE editor to have an option in embeding the flash to set the wmode to either "transparent" or "opaque".

This is very important because I'm working on the project that has a drop down menu. If the wmode of the flash is set to "" (blank) or "opaque" the drop down is hiding behind the flash. I need to set the wmode to transparent so that the menu will pop up on top of the flash.

I can fix it by temporarily disabling the module then set the wmode to transparent, but when the client edit the page again, it sets wmode back to its default value "". Using "Edit HTML" button found in the TinyMCE module don't work either...

Please fix ASAP.

Thanks a lot!
