描述

Description:

In its examples, the Gateway API uses "foo" in "Prefix Match". However, we can conclude that the HTTPPathModifier should also work on / as the path prefix match.

The PR #5254 PR demonstrates that / is not handled correctly.

Repro steps:

Follow the end-2-end test, which is added in #5254

Environment:

In our environment, we use docker.io/envoyproxy/gateway:v1.3.0. The bug is reproducible in the main branch, and is reproducible in v1.2.5
