[mediacapture-screen-share] getUserMedia media streams capturing issue in MV3 (chrome extension) with respect to constraints (#296)

Nitesh2503 has just created a new issue for https://github.com/w3c/mediacapture-screen-share:

== getUserMedia media streams capturing issue in MV3 (chrome extension) with respect to constraints ==
### Bug Description
When using the `getUserMedia` API in Chrome to capture audio from specific Chrome tabs using the `chromeMediaSource` and `chromeMediaSourceId` constraints, the API is not behaving consistently. The issue manifests as the error "Uncaught (in promise) DOMException: Invalid state error."

### To Reproduce
Steps to reproduce the behavior:

Get the streamId from the `desktopCapture` API
```
chrome.desktopCapture.chooseDesktopMedia(
      ["tab", "audio"],
      tab,
      (streamId, options) => {});
```
Here, tab` argument consists of the tab info

Use the `getUserMedia` API to get the streams
```
navigator.mediaDevices.getUserMedia({
  audio: {
    mandatory: {
      chromeMediaSource: "desktop",
      chromeMediaSourceId: streamId,
    },
  },
  video: {
    optional: [],
    mandatory: {
      chromeMediaSource: "desktop",
      chromeMediaSourceId: streamId,
    },
  },
}).then((streams)=>{});
```
Here, the "Uncaught (in promise) DOMException: Invalid state error." will occur

### Expected behavior
The `getUserMedia` API should consistently capture audio from Chrome tabs using the specified `chromeMediaSource` and `chromeMediaSourceId` constraints without resulting in an "Invalid state error."

### Screenshots
These are the expected beahavior :

### Desktop
OS : iOS
Browser : chrome
Version : 119.0.6045.199
Additional context
