[2.0.8] Cargo Wagon continually makes annoying noise in Map Editor

[Quadrophenic]

In the map editor, when a cargo wagon is placed on a track, it continually makes a loud rattling noise, as if it were rolling. This noise never stops.

This is easily reproducible:

• Open the map editor

• Place some track

• Place a cargo wagon on the track

[Donion]

It's the sound of the cargo wagon door opening. When you place it in the editor when the game is paused the wagon stays in its door opening state and plays the corresponding sound. Technically not a bug.
If you un-pause the game for a bit, the wagon door will fully open and the sound stops.
