Steps to reproduce:

VisibilityStateEntry is a new performance timeline entry type that tracks page visibility changes. It helps correlate other performance timeline entries with environment state.
New spec change: https://github.com/whatwg/html/pull/8206

See tests: https://wpt.fyi/results/page-visibility/visibility-state-entry.tentative.html?label=experimental&label=master&aligned

Actual results:

The above tests fail

Expected results:

I'm not sure if this is the best component for it, please feel free to change it to a more suitable one.
