Brown Mushroom Block texture is missing about minecraft-assets

[GalHorowitz]

Actually it seems that the texture content exists, but for some reason there are two keys with the name 'brown_mushroom_block', one which has the texture and the other is null. The null one overrides the real one. This is not the only block for which this happens.

looking at the image_names.js (the extractor script) it looks like it doesnt support 'multipart' blockstates (e.g. when blocks have different textures based on placement direction), which causes it to return null, not sure how it managed to extract one with the texture beforehand. (see https://minecraft.gamepedia.com/Model#Block_states for the multipart tag)
