Session replay and heatmaps for canvas elements

[saronic-tantona]

Describe the feature or enhancement

We've been evaluating Umami vs. Posthog and while we preferred Umami it's missing capturing canvas elements in session replays and heatmaps. Is this on your roadmap?

I may have missed something as well - apologies if so!

Looks like this might do it? #4308
