What is the 1st-party vs 3rd-party breakdown of sites with worst TTCI?

[addyosmani]

For sites with the worst time to consistently interactive, what percentage of these sites are loading JS from a first party origin ("site/app code") vs third party (maybe ads, widgets)?

This one may not be possible to compute without a change in Lighthouse that includes the 1st vs 3p breakdown. It may also be something we can calculate using WPT if we can figure out how to get the joins right.

I think you can modify that analysis to get a 1p/3p breakdown against TTCI measurements in HA?
