I think this looks good as a fix, but I was wondering if we should fix the rules or the code? We can make the existing rules work by changing the event names in the code, right? Or would we risk breaking ppls working rules that way?

Risk either way:

• If we change the code, the existing broken rules will start to work. Probably ideal, so probably better fixing the code
• But if they somehow managed to figure out these rules were broken and fixed them, then they'd break.

Merged in #12088, thanks!
