Integration with Tiddlywiki doesn't work

[ssveta7ak]

What happened?

Integration with Tiddlywiki doesn't work.

Now Tiddlywiki requires URI-decoded authenticated-user-header.
https://tiddlywiki.com/static/WebServer%2520Parameter%253A%2520authenticated-user-header.html

Thus, the Pomerium integration with TiddlyWiki is not working at the moment.
It redirects to the HTTP Basic Authenticator instead of IdP.

What did you expect to happen?
