Text overlap in admin panel breadcrumbs

[jefferyto]

Describe the Bug.

Text in different segments of the breadcrumbs may run long and overlap with each other:

I believe this is what is should look like:

This is caused by the removal of overflow: hidden in packages/ui/src/elements/StepNav/index.scss as part of #13683. I believe overflow: hidden was removed because it prevents the dashboard dropdown menu (with "Edit Dashboard" and "Reset Layout") from being visible and hides part of the "Editing Dashboard" view. But text-overflow: ellipsis requires overflow: hidden and that's why the breadcrumb text now overlaps instead of being truncated.

Reproduction Steps

Run the uploads test suite (from the monorepo): pnpm dev uploads
