Infinite "Paste" Attachment upload

Details: Browser - Zen (Latest Stable)

The file upload worked till this point in the chat with Claude 3.7 thinking. I guess I had uploaded 4-5 images before this message where it got stuck.

Tried refreshing the page, tried reloading the chat by switching to other chat and coming back.

Also, Using Firefox container extension & UblockOrigin
