How to use a token that includes slashes with PathAuto?

Question

I have a custom token that gets the path value from a JSON field. The JSON field stores the path like this (in the database, the slashes are escaped, but I'm showing an unescaped example here):

{ "path": "a/b/c" }

Every node contains this JSON field, so I made a custom token, [mymodule:json_path].

I then set this token as the path for nodes on the PathAuto patterns page (/admin/config/search/path/patterns).

However, PathAuto is stripping the slashes, so when I save a node, I get the path abc when I want a/b/c.

Elsewhere, when I use the token, I get the value with unescaped slashes as expected (for example, a/b/c); I know this because if I set a metatag on the node to the token, the expected value appears.

Also, if I disable Generate automatic URL alias and manually set the path to /a/b/c, then I get the expected path of /a/b/c.

So, how can I get PathAuto not to remove the slashes?

This can be done through the UI, at /admin/config/search/path/settings.

Scroll down to "Punctuation" at the bottom, expand it, find the Slash (/) option near the end of the list, and set it to something other than Remove.
