Improve subdomain fallback

See online.mbank.pl vs mbank.pl.
The first one only has 16x16px favicon.ico, but the second one has nice 180x180 favicon.

Subdomain may have completely different icon, I'm not sure it's a good idea to fallback to a domain's one.
Eg. https://mail.google.com/favicon.ico

In this case we'd have icon of the company who made the product instead of an icon of the product.
Is it really that bad? I think it's better than no icon.
And it works for the example I originally gave.

Anyway, fallback is not necessary here, so it's not a real case.
Any real-life counter-examples?

You're right, but my note was regarding this line:

The first one only has 16x16px favicon.ico, but the second one has nice 180x180 favicon.

Should we fallback to a company logo if we have a low resolution product logo?

In my opinion we shouldn't, but we can improve the algorithm by the comparison of subdomain's and domain's favicons and returning one with a better quality, if favicons are the same but with different resolution.
