Using Readyevent on scenario halts execution of BackstopJS

I'm trying to use the ReadyEvent to delay the execution of a scenario (B) that requires scenario (A) to be finished before (B) begins. (Basically scenario (A) creates a piece of content in my CMS and scenario (B) deletes it)

I thought the issues was in my custom puppeteer/backstop scripts but I tried it with a vanilla backstop and the ReadyEvent still halts everything.

Am I completely missing something and not using it right? or is this an actual issue with Backstop?

Any help would be really appreciated.
