[Web] Fix webview blocking js reload

Fixes #1335

If I'm understanding it correctly, this solution is to allow internal WebView reload requests to pass through without overriding loading.

I'm wondering if there's an alternative solution using some sort of unique ID to compare against instead of url != view.url to call view.loadUrl.

Then, instead of returning false here, we'd update the unique ID representing the particular request which would trigger a reload.

That might keep the number of codepaths down, and be closer to a more single-source-of-truth?
Not sure if that would change how we would want to do normal reloading.

Not that I could find, you get barely any information about the request. I couldn't even tell it was from a js event in this callback.

I was thinking about something like

    request?.let {
        state.content = state.content.withUrl(it.url.toString())
        state.requestId = UUID.randomUUID()
    }

And then that requestId could act like a key() to trigger a reload.

It's not quite that easy unfortunately because we also have to worry about if the page is displaying html data or a url. We don't get that information here to be able to update our state correctly. Worth investigating further in the future but will merge this fix for now.
