Killing and yanking attachment buttons loses face

[Uday Reddy]

When you kill and yank attachment buttons, they don't look like buttons any more. Can the face be preserved during the operation?

Hey Uday,

The problem, in this context, with the mime-buttons in VM is that the face is associated with an overlay and is not a text property. Overlays do not get preserved because they are buffer-local. Not sure why an overlay is used, but it is interesting to note that the text properties of these buttons contain the 'vm-mime-layout' as well as the overlay (this one gets yanked with the text)

Yup, see the "Extents and Overlays" in the Internals section of the VM
manual!

But I didn't realize that is what I ended up doing. I will check.

Cheers,
Uday

Attachment buttons are text-properties in Gnu Emacs. So there is no problem there.

The problem is that the font-lock-mode is overriding the local font setting. If I turn off font-lock-mode, it works fine.
