The builder for an indicator may not be set during right after indicator initialization. It's set after we fetch the measurement set. I'll push a patch with a tooltip in the indicator which will show a bigger scope of this feature.

Then we should just have a map between each indicator & builder in TestFreshnessPage. We shouldn't be adding an instance variable to FreshnessIndicator just because it's a convenient place to store things.

By the way, it's not great that this UI is only triggering from mouse from accessibility point of view. Maybe also make it possible to focus these indicators and trigger these when focus / blur? We can do that in a separate patch though. > Websites/perf.webkit.org/public/v3/components/freshness-indicator.js:78 > + a:hover, We probably shouldn't automatically highlight during :hover if highlighting is an explicit operation now. > Websites/perf.webkit.org/public/v3/pages/test-freshness-page.js:12 > + this._hoveringIndicator = null; I think more canonical way to name these things in perf dashboard codebase is like _currentlyHighlightedIndicator. > Websites/perf.webkit.org/public/v3/pages/test-freshness-page.js:151 > + const containerPadding = 0.3; > + const containerMargin = 0.3; Just get this out of the computed style: getComputedStyle(indicator.element()).paddingLeft.

How about 20rem?
