There's a discussion going on Village pump (technical) about custom signatures aka sigs. One user went above and beyond with their customized signature inquiring the community for input, two of which pointed out the reply button not displaying. I do not have the know-how to advise the aforementioned user to get the reply to work as intended, so I turned to you. The below signature is the sig in question: https://prnt.sc/O9RLhHZw4-hN
Your input would be much appreciated since you are the creator of the gadget.
