Great. That was annoying me for quite a while but I didn't realize it works on the inner component.
Let's keep this in for backwards compat since the next react minor should fix this.

Not really related to the diff in this PR, but what do we need memo for exactly? Was it added to prevent unnecessary re-renders or something?

It's one of the only components that doesn't accept a react element as a prop, so one of the few spots where memo can work on the library. Do we have a benchmark that shows the win on a real-life use case? No.

It's most likely worse for perf since SvgIcon almost never has an expensive tree on which we want to bail out. But now we have it so somebody might rely on it.
