Expected route selection prioritization with RegularExpression

[BadLiveware]

Route selection priority

It seems like its not possible to override routing selection via more specific matches using regex and query parameters,
I would expect that if two RegularExpression paths matches, other match attributes would be used as tie breakers, for example queryParams.

This is a simplified example:
Default everything to the backend old-web via PathPrefix: /
Override other HTTPRoutes to old-web on regex .* AND query parameter next=0
Match a specific route((/<i18n>)?/valuation) to nextweb
Try to override that route by going to /en/valuation?next=0, the selected route will be nextweb
Try to override that route by going to /en/valuation?ow=1, the selected route will be nextweb

What is the expected outcome of the route selection in this situation?
