Performance alarm bells are going off in my head... did you investigate perf
impact? (could be very minimal, just dunno)

Alas, I am still unaware of an metric that is anywhere near precise enough to
measure any such impact.

You're not wrong to be concerned, but it sucks that web UI is so slow that we
have to worry about this sort of thing.

I removed the <span> and it looks the same, hopefully just inserting <content>
shouldn't have any real impact when it is empty?
