Black screen sent to call participant when sharing screen while camera permission is not granted

Using a supported version?

• I have searched searched open and closed issues for duplicates.
• I am using Signal-Desktop as provided by the Signal team, not a 3rd-party package.

Overall summary

It used to be possible to share the screen without having camera permission granted. On or around an august 2024 update, perhaps 7.20, it's no longer possible. Signal asks the user which window, app or screen should be shared but only a black screen is sent.

Steps to reproduce

1. Start a call
2. Refuse camera permission
3. Share the screen

Expected result

Screen is being shared

Actual result

Black screen is shared

Hi there, I'll have a look to see what went wrong. This is my first open-source contribution; so forgive me if I'm a bit verbose. However, I'm a Software Engineer but now want to benefit humanity by contributing into open-source projects.
