Playground endpoint is printed even if it is not enabled

[alice17]

I have two paths for two chains configured for my app:

  add_routes(app, chain, enabled_endpoints=["playground", "stream_log"])
  add_routes(app,
             chain_with_sources,
             path="/rag-with-sources",
             enabled_endpoints=["invoke"])

Even if the second route does not have the playground enabled, the endpoint is still printed when starting the application:

LANGSERVE: Playground for chain "/" is live at:
LANGSERVE:  │
LANGSERVE:  └──> /playground/
LANGSERVE:
LANGSERVE: Playground for chain "/rag-with-sources/" is live at:
LANGSERVE:  │
LANGSERVE:  └──> /rag-with-sources/playground/
LANGSERVE:
LANGSERVE: See all available routes at /docs/

When I try to access /rag-with-sources/playground/ I get 404.
