Symfony version(s) affected: 5.0.8

Description
Adding custom function (via tag routing.expression_language_provider) causes fatal error in the routing tab of the profiler: the function does not exist.
If the route does not match, no errors

How to reproduce
https://github.com/JakeFr/function-in-routing
query GET:/api?foo[bar]=baz
and go to the routing tab in profiler

Possible Solution
Related to the AddExpressionLanguageProvidersPass, UrlMatcher and TraceableUrlMatcher but i cant find how to fix
