On route match, routes parameters are not shown in the debugger panel (when the pattern /hello/{name} is used to match the /hello/world url, we should see name => 'world' in the upper table of the panel - nothing is shown instead).

This seems due to the fact that the table data are based on request.routeParams which come from the RequestDataCollector however this parameter is not an array as expected but it has been previously transformed to a string representation.
