Link rel generated by Javascript is not properly evaluated

[vladimir-aubrecht]

Some pages are generating url to link rel by javascript, but FavIcon currently cannot evaluate it and as a result icon is not recognized.

Sample webpage: https://www.dcuniverse.com/
Actual link: <link rel="icon" href="{{\'images/favicon.ico\'| buildPath}}" type="image/png">
Expected link: <link rel="icon" href="https://www.dcuniverse.com/builds/892ed368/images/favicon.ico" type="image/png">
Correct href: https://www.dcuniverse.com/builds/892ed368/images/favicon.ico

@vladimir-aubrecht wow, ok, this will be hard to fix, since we just use URLRequest, and then parse the HTML without further interpretation.

the only way I can see this working would be to spin up a webview of some kind, use that in a headless mode, waiting for some signal that the JS has finished rendering the template, and then walking the DOM to navigate the <link> elements.

every day, frontend guys do something new to surprise me :)
