What specific section or headline is this issue about?

Browser Compatibility

What information was incorrect, unhelpful, or incomplete?

The focusin / focusout events seem to be supported by all major browsers as of today, and caniuse also lists them as supported. The MDN page however lists them as Limited Availability and suggests it is not supported in Firefox, Chrome or Edge.

What did you expect to see?

A checkmark for Firefox, Chrome and Edge, as well as a compatibility table.

Do you have any supporting links, references, or citations?

Caniuse listing the events as Baseline available: https://caniuse.com/?search=focusin
