If I understand this correctly, the `BroadcastChannel` API solves a similar purpose.

I came to say this as well. Surely it is the proper way to do this. Could be combined with weblocks if you want some master/leader event bus tab or web worker

Oh, did not know about it :D Thank you! Added a link to this to the TabSub landingpage

My pleasure—happy to share an alternative. Thanks for making and sharing a thing!
