Missing favicon.ico is blocked by CSP?

Correct, this is done by the browser by default. But 'the world' hasn't seemed to be able to come up with ONE single solution to this, but each developer has to figure out how to go about it themselves. It SHOULD have been dealt with in the browser, as in: the browser makes a request for a favicon.ico (lame defaulting if you ask me), it then gets a 404 error ... now, from here on the browser should simply ignore this. This is pure ising, and has nothing to do with things 'breaking' or not working properly and what not ... so, basically implemented with no thought going into it, really.

And this was initially 'invented' by Microsoft ... so, no wonder it's flawed like hell.
