When clicking on one of the cards from the home page of the docsite and
when initially loading the home page of the docsite, the webviewTag was
emitting a `did-frame-navigate` event, which we weren't tracking. This
meant that we were not properly recording that a navigation had
occurred. This caused three separate issues:
- We were never setting the meta url for the block, which meant that
when you navigated to a different tab or reloaded the app, you'd lose
what page you were last on.
- The site would reload after we fixed a broken docsite url, but we
wouldn't remove the error text that blocks the broken site.
- Clicking on the "open in external browser" button wouldn't do
anything.
