Are you seeing this after you refresh the page with devtools open? I'm seeing them all disabled if I open devtools with an existing page, but refreshing the page makes them show up.

I think this is because that script has already been GCed, so we don't get any breakpoints for it.

Yes, this is a GC issue. This works on refresh. Is there a bug that I can dupe this against?

This bug is likely a good dupe.
