If you edit https://glitch.com/edit/#!/vine-sponge?path=index.html:64:9 you can see there’s a scary red dot in the left margin. Usually this indicates some sort of breakpoint, or maybe error. But I don’t see any indication of what the error or breakpoint is. Hovering my mouse over the dot does not help.
Does anyone understand what Glitch is trying to tell me here? Maybe I’ve found a Glitch bug?
