webview: Allow opening some links in the user's native browser

[straygar]

By default, all links you click in your webview load in the same window. However, in some cases I want to open the linked page in the user's native browser, rather than my app.

Not sure what the implementation would look like. It could be either

• based on some rule (e.g. "load links in the same hostname in the webview, others - native browser")
• by exposing an "onNavigation()" hook that can let me choose when to do block the webview navigation and open the native browser instead.
• putting the burden on the embedded page - e.g. add some special prop to the <a> tags, or assume that any <a target="_blank"> should open in the native browser

Well, thanks for the FR, but I think you could already do that without needing to change the webview class.

If you use a global click listener that intercepts all clicks on tags, you could bind a C++ function and call it with the link if you want to handle it in a special way.

@julianstorer Good idea. I guess along with clicks, we also need to intercept any kind of "Enter" presses on links, any kind of programmatic navigation triggered from javascript (e.g. window.navigate()).

Feels like it's easy to have some stuff fall through the cracks if we try to intercept stuff that causes a navigation, rather than the navigation event itself.

Yes, fair point, there probably are other ways to navigate. It's a valid FR, as I assume the webviews will have some way of intercepting redirects
