Steps to reproduce
Array
, and add a method that callssuper
What is expected?
The computed value should update
What is actually happening?
Computed value does not re-evaluate
System Info
Any additional comments?
This was working in beta.1, and stopped working in beta.2. This failure is different from versions >= beta.3 though. In beta.2, the source value does not update, so it's unclear if the computed property would have re-evaluated.
This regression is likely related to fixes from earlier tickets,
#11570
#11573
#11628 ← this was very similar, but it accessed item by index instead of method
