Extra config not being honored on demo

[every-time]

Have you read the FAQ and checked for duplicate open issues?
Yes.

What version of Shaka Player are you using?
v4.15.2 (uncompiled)

Can you reproduce the issue with our latest release version?
Yes.

Are you using the demo app or your own custom app?
Demo app.

What browser and OS are you using?
Windows 11, Chrome 137.

What did you do?
Tried to play a stream (M3U8, Custom Widevine License Server URL, and "Authorization" License Header with value was provided) with the following EXTRA CONFIG:

{
  "networking": {
    "forceHTTPS": true
  }
}

What did you expect to happen?
For the stream to play with HTTP URLs being requested with HTTPS.

What actually happened?
It's still attempting to play with HTTP URLs. And when I check extra config again, it's "reset" to:

{
  "networking": {
    "forceHTTPS": false,
    "forceHTTP": false,
    "minBytesForProgressEvents": 16000
  }
}

Also, clicking the REPORT BUG button throws this:

Uncaught (in promise) TypeError: Cannot read properties of null (reading 'forceHTTP')
