I plan to work on this bug to provide a patch but as I may not be able to do this without your hints, suggestions and recommendations on how to get plugin code out of rendering tree.

According to current HTML5 spec, plugin life-cycle should not be affected by CSS properties (on embed, object and applet elements).
http://dev.w3.org/html5/spec/Overview.html#dfnReturnLink-44
"The embed element is unaffected by the CSS 'display' property. The selected plugin is instantiated even if the element is hidden with a 'display:none' CSS style."
http://dev.w3.org/html5/spec/Overview.html#dfnReturnLink-156
"The above algorithm is independent of CSS properties (including 'display', 'overflow', and 'visibility'). For example, it runs even if the element is hidden with a 'display:none' CSS style, and does not run again if the element's visibility changes."
http://dev.w3.org/html5/spec/Overview.html#the-applet-element
"The applet element is unaffected by the CSS 'display' property. The Java Language runtime is instantiated even if the element is hidden with a 'display:none' CSS style."
