How we will display the success and alert pieces are still to be discussed, but this is a way to show how they will appear on the section title.

Here is how your PR affects size of JS and CSS bundles shipped to the user's browser:

Sections (~816 bytes added 📈 [gzipped])

name           parsed_size           gzip_size
site-profiler      +2461 B  (+2.6%)     +816 B  (+3.2%)

Sections contain code specific for a given set of routes. Is downloaded and parsed only when a particular route is navigated to.

What is parsed and gzip size?

Parsed Size: Uncompressed size of the JS and CSS files. This much code needs to be parsed and stored in memory.
Gzip Size: Compressed size of the JS and CSS files. This much data needs to be downloaded over network.

I have reviewed the components, and they look great. I have left a non-blocking comment that can be addressed in this or in a follow-up task

What do you think about creating a component to encapsulate all the display logic of advanced metrics? I was thinking in something like <AdvancedMetrics... that will accept an array of refs (or just all the refs as different props) and the response of calling the /site-profiler/advance endpoint.

That way, all the logic to iterate the response and decide what titles to show will be handled in a separate component that can grow independently of this one.
