Shown length of voice messages is always inaccurate

[NetSysFire]

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

This is pretty much exactly #6908, except that this is a supported signal desktop build. The issue has been present since quite some time but I could never bothered to report this until now. This is a minor issue as the effect is purely cosmetic and does not actually affect how a voice message is played.

Steps to reproduce

1. Receive any voice message from a user.
2. Play the voice message.

Expected result

The timer and progress bar matches the length of the voice message exactly.

Actual result

The progress bar and timer reaches its end too soon. Any voice message is pretty much always a couple of seconds longer than the UI expects. I think this scales with length, the longer the voice message, the higher the inaccuracy.

With a 2 minutes and 18 seconds long voice message I got ~11 seconds of inaccuracy.

Voice message as displayed in signal desktop:

The very same voice message as displayed on my linked Android phone:

The sender of the voice message also uses Android.

In app.log I see the following events spammed after the voice message exceeds the expected length:
