I have one important comment to address that could impact a rework of this PR. Therefore, I wait until we resolve it before giving this a more detailed review.

[philipphofmann]

m: I think we must add to the code docs of the option enableTimeToFullDisplayTracing that this also has an impact on the SentryTracedView.

Almost LGTM.
