MacOs UXP webview for Photoshop is missing file selector

Hi, I am trying to make plugin in UXP that is using webview to render some webpage. The webpage itself is using inputs with "file" type. Unfortunately clicking on such input does nothing on MacOs (it does work on Windows though). From what I see in Safari webview documentation it requires implementing some methods on webview delegate. Can anyone from Adobe confirm that this is planned feature? It would be nice to have it working on MacOs too.

Here is link to mentioned webview documentation:
