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

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

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.
