Chained showModalDialogs that earn a new user gesture in the popup window.

Multiple calls to showModalDialog within the same event handler are associated with the same _WKUserInitiatedAction

If a page calls showModalDialog in response to an onclick handler, its JavaScript execution is paused. We see an enterprise UI pattern where the onclick handler for a button will spawn a sequence of dialogs, each collecting some user gestures.

If the spawned dialog was interacted with before closing, then subsequent calls to showModalDialog should get a new _WKUserInitiatedAction.

The attachment has a reduced example of this behavior.
