Visible border line around voice message animation

[ExtRIELICi]

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

There is a visual bug that occurs in certain situations. For example, when playing a voice message, clicking on it while it is playing, and taking a screenshot, a border line appears.

This is a minor issue and could be considered normal behavior, but I am reporting it for the sake of completeness and to help improve the user experience.

Steps to reproduce

1. Open Signal Desktop on macOS (just for reproduction purposes)
2. Send a voice message
3. Play the message you sent
4. Click on the voice message timeline
5. Take a screenshot using Shift + CMD + 4
6. A dark line should appear around the voice message timeline

Expected result

Taking a screenshot while playing a voice message should not cause any visual artifacts or unexpected UI elements to appear.

Actual result

When playing a voice message, clicking on it while it is playing, and taking a screenshot, a border line appears, which is a visual bug.
