Endpoint list with render-styles 'focused' and 'read' is not displayed correctly

[sag-camos]

We have an API with a lot of Endpoints and use the render-style 'focused'. We noticed that the endpoint list on the left is cut at the bottom and not all endpoints are listed (see picture).
The issue only occurs when initialy loading the specification, when collapsing and expanding the list, it is displayed correctly.
We had problems with that, because some endpoints could not be found at first sight.
The issue also occurs for render-style 'read'.
I added a sample json-file for reproduction.
