Hi Binyamin,
Thank you for your question.
I think this behaviour should be left to the implementation there is a
lot of UI decisions here that can't be spec'd. For example, Chrome would
likely pick a 32x32 image when it needs a 16x16 one but might not do the
other way around. Some UA might avoid taking a 32x32 image instead of a
16x16 image because one is twice as big as the other and might not be
optimized to be seen as small. Obviously, all browsers should do a best
effort in picking an image.
