This looks like a bug in Metacity, I don't see why it adds "(disabled) decorations"
when only asked for MWM_DECOR_BORDER. On the other hand we already check for
WS_CHILD|WS_POPUP and don't add MWM_DECOR_BORDER if any of that styles present,
so perhaps your change is in that direction, and should be made to also check
for both WS_CHILD|WS_POPUP.

Probably it's also worth to file a bug to metacity bugzilla.
