App-to-Web Click Source Registration

[jfggit]

I'm trying to follow along with the documentation both here and in Android docs and I'm not quite sure how or if the following works, or if it does, how exactly.

In the scenario where an app is using a WebView purely to display an ad (i.e. non-browser-like app), we have a simple display ad with an image wrapped in an anchor tag like:

<a href="[click tracker + landing page URL]" attributionsrc="" target="_blank">...</a>

I believe this case would result in Android opening up the default system browser to load the URL (let's ignore the case where the app/ad SDK intercepts the click and handles it differently). Can this click be registered? Will the WebView be able to delegate to registerSource for this type of event? It seems like the WebView is actively being paused/discarded if the context is switching over to a browser, right? If the default system browser is Chrome, would the request made to the click tracker server be registration eligible (i.e. would Chrome inherit the registration eligibility from the WebView click context)? Which context (WebView or browser) would be attempting to register this source event, if any?
