Summary [Qt] QWebPluginFactory: plugin widgets gets deleted on "display: none"

This bug report originated from Nokia internal issue QT-1181 --- Description --- In the Documentation for QWebPluginFactory::create we mention that ownership of the returned object will be transferred to the caller. Maybe we could elaborate more. For example one customer had problems with how to hide a plugin. When using a qt widget plugin or in general any <object>, they get deleted on display 'none'. This means that on showing it again, one have to restore the new plugin/<object> to the _exact_ state as before it was hidden.

Not platform related. Changing to All.

The documentation seems ok to me, we could add details about the object livecycle. As I understand hiding/showing the surrounding container will delete/create the plugin. This is more dramatic and might be very annoying depending on the use case. We need a test case.

IMHO this is INVALID. In Qt 4.4's WebKit there was a bug that the plugins never got deleted at all (leak). In Qt 4.5 we fixed the leak and now behave like the other ports when it comes to plugins: With 'display: none' the render object is destroyed and thus the plugin widget. There's nothing Qt specific here.
