@ericregnier
I don't see that we support the addOnReadyStateComplete and removeOnReadyStateComplete methods for the control.
I didn't find them in the documentation. There are methods that exist, but if we don't document them, they aren't supported.

This shows the methods supported for an IFrame Control: iframe control type methods

Am I missing something?

Hi @JimDaly,
For iFrames, shouldn't the event be supported, as we can set a handler in the classic UI?
For web resources, the documentation states that "A web resource control has the same set of methods available as the iframe control. See iframe control type" and so I assume the same event is supported for web resources. I can confirm that it works (I know it doesn't mean that it's supported thought).

Can you comment on whether we can add Eric's change to the docs?
