XYChart Tooltip not firing

[lapidus]

I am rendering XYChart in an iframe and some additional providers.
I've tried to figure out if one of the other providers are interfering with <TooltipProvider> but no luck so far ...

The same chart renders fine with tooltip, outside these particular wrappers. Any ideas appreciated on what could cause the XYChart tooltip to not work in this context. (The regular @visx/tooltip works fine within the same iframe environment.)
