Namespace open is incorrectly reported as redundant


Compiler doesn't recognize static method in auto-open type ([source](https://github.com/Lanayx/Oxpecker/blob/develop/src/Oxpecker.Solid/SolidRouterBindings.fs))


**Repro steps**

1. Create empty project
2. Add Oxpecker.Solid nuget package
3. Add the following code
```fsharp
open Oxpecker.Solid.Router // editor incorrectly suggest to remove this open

let test() =
let nav = useNavigate()
nav.Invoke("/")
```

**Expected behavior**

Open removal is not suggested

**Actual behavior**

Open removal is suggested

**Known workarounds**

Ignore the suggestion
