Thanks for the PR! I'm happy to help get this merged in. I tried out the
proposed patch locally and it does address the issue in the case identified.
However, I tried to run in some of the other context and the filter was not
running as expected. Adding a dispatcher type of FORWARD on the
`SanitizeContextPathFilter` resolved the issue locally. With this update I'll
be a +1.---
