[Windows] Don't paste files if the clipboard has an image
(Originally found on Windows v1.15.3, tested just now on v1.15.4, still occurring)
If I right-click an image in Firefox and choose to copy that image from the drop-down menu, then go into a conversation in Bluebubbles and press Ctrl-V to paste that image into the conversation, it results in two identical images being added to the message I'm about to send. I can delete one and hit send and it will work just fine, but if I don't, it will send a separate message for each of the images and whatever text I've sent alongside it.
This does NOT happen if I copy the image from Chrome or Edge, only Firefox (v173.0.1 currently, but not just that version).
This is likely because it's being copied to your clipboard as both an image and as a file, and these versions added support for pasting files from the clipboard. I should disable file paste if an image is on the clipboard.
I can verify that if I hit Ctrl-V on my desktop, it does indeed paste a file, so it looks like you're right about that. I didn't even realize that was something Firefox did.
