Compiling krane's scml output does not produce same-looking animation

[myxal]

I've (re-)made a trivial animation project for the freezer - just 2 textures, 1 for each animation of "open" and "closed": freezer.zip

The images have a large transparent area around them - after compiling with scml, decompiling the result with krane, the sprite's opaque part appears to have stretched into the size of the original image. This is also visible when opening krane's output in Spriter:

This is then also visible in the game, after compiling krane's output with scml.
