Dataframe in a webview breaks on Mac in another tab

[Josef-Haupt]

Describe the bug

Hi! I am creating a GUI for an application which will be deployed cross plattform. To make it look like an app I'm using pywebview, which has been working fine one my machine (win10).
Currently I'm trying to make it work on Mac also.
The only problem is that the dataframe only works in the first tab (see example).
No matter what contents I try to serve, nothing will be displayed in the DF in the second tab.

Reproduction

import gradio as gr

    with gr.Tab("Second"):
        gr.Matrix(headers=["h1", "h2"])

url = demo.queue(api_open=False).launch(prevent_thread_lock=True)[1]

webview.create_window("foo", url)
webview.start(private_mode=False)

Hi @Josef-Haupt I'm not super familiar with pywebview but if the Gradio app works correctly if you launch it like demo.launch() but not if you use pywebview, then it would suggest an issue with pywebview, correct? I would suggest opening an issue on https://github.com/r0x0r/pywebview

Pretty sure they are going to say the same thing.
Pywebview only uses the platforms native GUI, which is cocoa on macOS, to create the webview basically a Safari lite.

Got it. I think this is outside the scope of Gradio right now, but we do have an open request to be able to build desktop apps with Gradio: #2257

Its a bit far down in the roadmap, but feel free to follow that issue for an officially-supported solution to build desktop apps
