Cubase adds silence when exporting mp3

As discussed here https://www.gearslutz.com/board/steinberg-cubase-nuendo/1224019-cubase-audio-export-inserts-silence-beginning-file.html?posted=1#post13428976, Cubase 9.5 inserts silence at the start of an exported mp3-file.

How to reproduce:

  1. Generate an Audio Click with the default click sound
  2. Export as mp3
  3. Open file in an other editor than Cubase (for example Audacity)

See attached screen capture. On top is an mp3, below is a wav exported from the exact same project.

Update. Not a bug, just the way mp3 encoders work. Thanks @Grim!
