There seems to be a bug in the <> SCRIPTS
section of the Entity properties tab. The order of the icons goes out of order, making it impossible to drag, and to click on some of its attributes. Moreover, the individual script’s ON/OFF toggle and trash can icon are gone altogether. This seems to only affect Firefox, it looks good on Chrome/Safari.
