I think this is non-blocking since it feels like something we can tweak later, but the PVC component only shows focus on the whole editor when the textarea is focused. When focus is on the toolbar, the blue outline around the editor is not rendered. For example:

Screenshot of PVC commentbox with focus on a toolbar button. One blue outline is visible around that button.

The same is not true for this component, where we show the outline whenever focus is anywhere inside the editor:

Screenshot of React commentbox with focus on a toolbar button. Two blue outlines are visible: one around the button and one around the entire commentbox region.

The problem is how we would do this: has would be the perfect solution here (&:has(textarea:focus), but browser support is not there (thanks Firefox). Maybe it's worth waiting for browser support rather than rolling some custom React state-based solution.

Should we capture this in a new issue? It seems like Firefox will support :has by Christmas: https://groups.google.com/a/mozilla.org/g/dev-platform/c/oacuvZ2_hLg/m/4o28pFLkAwAJ?pli=1 🎉

Oh that's interesting. We already use :has in primer/react in a few places. I'm assuming this is because dotcom uses a polyfill
