Dragon wings spasm after back throw

Title:
Midori’s Dragon form’s wings will spasm after a back throw.

Summary:
When doing a point-blank back throw from the left side (Midori’s on the left, target is on the right), Midori’s wings will continue to spasm until you move or do a maneuver.

Steps to reproduce:

  1. Go to practice mode.
  2. Choose Midori as 1st player.
  3. When the match starts, transform into Dragon mode.
  4. Walk up to the target from the left side until the pushboxes collide.
  5. Do a back throw and do not press any buttons afterward.

Expected Results:
The dragon’s wings do not spasm after performing the back throw.

Actual Results:
The dragon’s wings will constantly spasm very quickly until you move or do a maneuver.

Notes:
I only tested this in practice mode. It seems that throwing from further ranges does not always cause it (there was at least one time it did not trigger from point blank), nor does throwing from the other side (have not seen it trigger once).
