"Fast-forward and Fast-rewind" command is not working

Expected behavior

When listening to music with the player, I tried to press and hold the next button to 'fast forward' the music.

Actual behavior

When I pressed and hold the next button, the music was still playing. I tried to do same in the reverse, but it keeps on doing its (previous and next) command.

How to reproduce the bug:

• Install the app from F-Droid here
• Play a song
• Press and hold either previous or next button to fast forward or fast rewind the song
• Browser: Vanilla Music Version 1.0.60
• Operating system: Android Version 7.0
