On mobile we're space constrained and only show the first and last breadcrumb. Some apps like Phriction and Diffusion, this may be sub-optimal. Unclear what is a "good" option here, but maybe collapse the crumbs into a dropdown menu on the last crumb itself?

Original ticket:
This is kind of annoying on mobile, but there's no direct way to navigate to the parent document of a wiki page in Phriction on mobile, without editing the URL or navigating back to the root of the wiki and going through the hierarchy again.
