Items do not line up with Chiseled stone brick block

When testing textures to find bugs like an example would be the kelp blocks top lines not connecting to the lines on the side (fixed) I noticed that glass, and iron bars do not fit symmetrically inside the chiseled stone brick blocks. I haven’t tested to see if any other blocks don’t fit symmetrically inside. Hopefully this is a bug, but if it’s not then that’s ok.
