Servers block regression in v0.111.0

[iann0036]

Hi,

For the following schema:

openapi: 3.0.0
info:
  version: 1.0.0
  title: Repro
servers:
  - url: https://something/v1
paths:
  /path1:
    servers:
      - url: https://something/v2
    get:
      summary: some path
      description: ''
      responses:
        '200':
          description: 200 OK
  /mypath2:
    get:
      summary: attempt to find this route
      description: ''
      responses:
        '200':
          description: 200 OK

A gorillamux FindRoute for the /mypath2 fails in v0.111.0. For the same test in v0.110.0, the route is found.

Suspect it relates to the work from #705. Note the exact naming of the paths somehow affects the reproducibility of this bug.

^^ as referenced in that issue, I'm also finding regressions here. Additionally, I'm having to add my API versioning prefixes to my servers block in the OpenAPI spec in order to properly pass validation. This means we are not properly matching on hostnames, but also on paths.

I will try to find the time to expand the test suite of the relevant code to hopefully give us more clarity here
