DoDs sometimes don't render on hover

[ikesau]

Saloni noticed this when changing tabs on this deprecated COVID chart

dod.rendering.issue.mp4

I can reproduce on Firefox 134, but there's no console output indicating an error. Presumably something is going wrong with the global event listener we use to power DoDs, or maybe it's to do with the fact that this DoD is inside a bold tag.

Additional investigation required.

Might be related to how bolding ends up being nested. Needs some investigation.
