unwanted design added automatically

Summary

Whenever a screenshot (for bug reporting) is pasted into an issue, it gets automatically added to designs (if the user is a Developer) This forces me to delete the design afterwards every single time

this issue is related to #230286 (closed) in the sense that for regular bug reporting we don't really want the Designs there

This last part wouldn't be a big issue if the pasted screenshots didn't get added to design

Steps to reproduce

As Developer, take a screenshot, then start writing a reply to any existing issue and press Ctrl-V The Image gets added to both the reply AND the Designs
