FlxAtlasFrames.fromSparrow jitters when flipX is true

[Geokureli]

This xml and the png below jitter when animating the walk animation while flipX is true, same happens when it is flipped through animation.add too. They said it works if they change all the frame's frameWidth to the 295. So I assume its an issue with flipX with different frame widths or something.

Here's a video of the issue: https://imgur.com/k3qLebb
