Cropped pixels on rotation

Hello, I'm trying to draw images using the Graphics library. I have a few small scale images (11x11px) which need to be displayed in different rotations. To save bytes, I am attempting to use the rotate option, as in:
g.drawImage(img, x, y, { rotate: Math.PI })
The image is drawn, but the end result has a 2px wide crop at the bottom edge. Is that a bug? Btw where can I find the bug tracker of this project? I am sure someone else ran across this before but I couldn't tell
Thanks!

Possibly this one? https://github.com/espruino/Espruino/issues/2435

Thanks for the links.
That doesn't seem to be the same problem, though.
I will try to find it and raise otherwise

It'd be great if you could come up with an example if you're going to file an issue. I guess you mean something like this?

var img = {
  width : 8, height : 8, bpp : 8,
  buffer : new Uint8Array([
    3,3,3,3,3,3,3,3,
    3,3,3,3,3,3,3,3,
    3,1,1,1,1,1,1,3,
    3,1,1,1,1,1,1,3,
    3,1,1,1,1,1,1,3,
    3,1,1,1,1,1,1,3,
    3,1,1,1,1,1,1,3,
    3,3,3,3,3,3,3,3,
  ]).buffer
};
g.drawImage(img,4,4,{rotate:Math.PI});

It definitely feels like there is some kind of issue there - seems to be missing at least the right and bottom edge...

Issue raised here. Thanks for the sample code btw
