MadiaStreamTrack zoom capability not returned in Android WebView but works on Chrome

Question

As shown in this article, calling navigator.mediaDevices.getUserMedia() as follows should grant zoom permissions:

const stream = await navigator.mediaDevices.getUserMedia({ 
    video: { zoom: true }
});

Also, as stated in the same article:

MediaStreamTrack.getCapabilities() returns a dictionary with the supported capabilities and the ranges or allowed values. Correspondingly, MediaStreamTrack.getSettings() returns the current settings.

With the information above I've done some testing in an Android device in both Chrome and in the Android WebView. The tests were made using this demo found in the same article.

Here are the results:

Chrome:

• Detected version on Chrome
• Capabilities detected on Chrome
• Settings detected on Chrome

WebView:

• Detected version on webView
• Capabilities detected on WebView
• Settings detected on WebView

As you can see in the "Capabilities detected" and "Settings detected" images, in the WebView the zoom capability is not shown while it is shown in Chrome.

Have I done something wrong or is there a bug on the Android WebView?

Seems it's a chromium issue and I don't think anyone is working on it
