fix(store): snapshot subscribers before notifying - #185
Merged
Conversation
notifySubscribers iterated the live subscribers array, so a callback that unsubscribes during notification spliced the array under the for...of iterator and silently skipped the next subscriber (and could double-invoke one added mid-notify). $onAction already snapshots its listeners; $subscribe now gets the same treatment.
