Speedlines rendering broken on WebAO

[MaxNMV]

Speedlines appear incorrectly on WebAO. The same sprites render properly on the Client.

Steps to reproduce the issue.

1. Use a sprite that utilises the speedlines.
2. Use another sprite that does not use speedlines.

behavior on WebAO:

Before using speedlines

Using speedlines

After (using a sprite without speedlines)

behavior on Client:

Before using speedlines

Using speedlines

After (using a sprite without speedlines)

Expected behavior:
Speedlines should render correctly on WebAO, consistent with the Client.

Thanks for documenting it, I am aware of the issue, it has popped up with the file extension change but I haven't found a good fix yet.
