Michal Mocny <mmocny@chromium.org> wrote:

[soft navs] Create InteractionContentfulPaint performance entry.

Replaces the use of the existing LargestContentfulPaint performance
entry as a mechanism for emitting "soft LCP" paint timings. The exact
criteria, timing, and semantics are entirely unchanged in this patch,
just the name of the entry.

The single biggest side effect is that now observers of LCP performance
entries on the performance timeline will not get a single merged list of
paint timings, when observing buffered entries. Now, these two timings
are isolated and have their own unique buffers.

Future work will change this performance entry and some of its
semantics.

This patch also significantly refactors some of the older soft-nav WPT
tests as part of getting them to work with the new API.
