Hey beth, should this be treated as a metabug?

Attachment: Bug 1937147 - Always emit experimental-pane-loaded to temporarily fix GenAI test r?mconley

browser_genai_init.js is currently failing due to expecting Firefox Labs
to always render in about:preferences. However, now that it is driven by
Nimbus, it only render if we know about any opt-in experiments. Since
the test doesn't create any, Firefox Labs doesn't render and the test
fails.

However, the test only waits for an observer notification and stubs out
that actual implementation that builds the page. If we emit this
notification when we decide not to render Firefox Labs then the test
will fail.

This will be removed in bug 1951311.
