Adds the
soft-navigationsandinteraction-contentful-paintfeatures as part of the Soft Navigations and Interaction Contentful Paint spec supported by default in Chrome 151.There is an argument that these are one feature, instead of two, since they are in the same spec, were released at the same time, and the main use case for
interaction-contentful-paintat present is for measuring LCP for soft navigations, however I have decided to split this into two features for a number of reasons:interaction-contentful-paintis likely to be split into it's own spec in the future.interaction-contentful-paintis emitted even when no soft navigation occurs and has use cases beyond soft navs.Let me know if you disagree.
Depends on w3c/browser-specs#2593 landing first.
Note the BCD data depends on this PR: mdn/browser-compat-data#30195 so is commented out for now.
