AFAIK, fontification can be obtained through either "overlays" or "text
properties".

When overlays, it is in the buffer itself, and not copied across other
buffers.

When text properties, it is a property (face) "attached" to the text, and thus
copied across other buffers.

So, it comes down to how fontification is made in the particular mode or
situation you face.

Best regards,
