Weirdness with wrapped handler and embed FS (static files)

Issue Description

I generally use /static/* for our static file hosting (when we host them via echo) and I usually have embedded FS for these files. This works fine usually but today something weird happened.

I changed the path to, for example, /x/static/* with everything else being the exact same and the static handler raises a 404 for the files. If I remove the /x it works just fine again.

The logs show the path is correct, the only difference is the leading /x .

Expected behaviour

Static files are served regardless of static url path

Actual behaviour

Doesn't actually serve regardless of path

Steps to reproduce

Create an embed FS containing static files and a http FileServer to handle them. Wrap them in echo and watch them work (or not)

Working code to debug

// embed.go

var (
        //go:embed static
        StaticFS embed.FS
)

// main.go (static files served correctly)

package main

func main() {
    e := echo.New()
    staticHandler := http.FileServer(http.FS(gohome.StaticFS))
    d := fmt.Sprintf("/static/*", config.StaticURL)
    e.GET(d, echo.WrapHandler(staticHandler))
    e.Start("127.0.0.1:8000")
}

// ALT main.go (only 404's on static files)

package main

func main() {
    e := echo.New()
    staticHandler := http.FileServer(http.FS(gohome.StaticFS))
    d := fmt.Sprintf("/yz/static/*", config.StaticURL)
    e.GET(d, echo.WrapHandler(staticHandler))
    e.Start("127.0.0.1:8000")
}

May be user error on my side but I can't find where that error is.
