I think this code can be moved into a function in HTMLPluginImageElement and shared between HTMLEmbedElement and HTMLObjectElement. You also need to do the same thing now for HTMLAppletElement. You also want to null check page.

Sure thing.

Page gets null checked on the first line, but yes. :)

Moved logging into SubframeLoader to catch all plugin subtypes, including HTMLAppletElement.

Do we have a guarantee that serviceType won’t be the empty string or null?
