Arrow key direction doesn't change music seeking direction

[librick]

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

I sent a .wav file to someone on Signal. When I use the arrow keys to seek through the audio playback, every arrow key regardless of direction (left, right, up, down) seeks forward. I think the seek direction should be different for different arrow key directions.

I'm running Debian/Linux but my locale is en_US and I haven't changed my keymap at all. My arrow keys work as expected in all other programs.

Steps to reproduce

1. Send a .wav audio file to your self (Note to Self)
2. View the audio message on Signal Desktop
3. Click the audio play button
4. Click on the middle of the waveform to seek
5. Hold down the left arrow key
6. A solid border appears around the waveform
7. Note that the track seeks forward

Expected result

• If I press the left arrow key, the track should seek backward
• If I press the right arrow key, the track should seek forward
• If I press the down arrow key, the track should seek backward (this might be debatable)
• If I press the up arrow key, the track should seek forward (this might be debatable)

Actual result

No matter which arrow key is pressed, the track seeks forward.

Screenshots

This is the UI that appears when you've clicked on a track and started holding down an arrow key. Not shown is that, regardless of which arrow key is pressed, the track always seeks forward.
