fady out of curiosity what are the 'plugin' elements for and why doesn't webview
need one?

[Fady Samuel, 2014/07/08 19:23:57]

Doh! I misspoke earlier. WebView has a browserplugin element. The purpose of
this custom element is to listen to attribute changes on the <object> and
respond to them appropriately.

So I should put that line back in? Perhaps we should name it something else so
that it is more clear that it is webview-specific.
