Related To: https://github.com/github/primer/issues/4367

This PR is part 2 of breaking apart a larger PR into grokkable parts.

Apologies for the larger PR but there was an odd interplay with the specificity across the various components that made it hard to break this PR into smaller chunks

Avatar is converted #5221

Suggested change

	.AvatarContainer[data-size='small'] {
	.AvatarContainer:where([data-size='small']) {

[randall-krauskopf]

Hi @jonrohan, I'll get these changes in. Quick question though, why is :where preferred over the bare attribute selector?

[jonrohan]

Where will reduce the specificity on the attribute selector and make it easier to override the styles in dotcom. We try and add it whenever the attribute lands on the same dom node where we add the passed in className
