OP is trying to share an image clipped using the pen with someone in chat (hence the Facebook messenger reference) so scrapbook while useful for other things won't help much.
I just tried to clip something and share to regular Facebook application and that works fine. I do not use messenger but I'd suspect that that application is to blame. Try sharing to other applications and see if things work as expected. You may have to find a workaround like saving to gallery first.
