Reproduction Link
https://jsfiddle.net/szzrLcr5/
Steps to reproduce
With the dynamic binding setup as shown in fiddle:
Enter the numbers into the table for some time. The application gets slower until it crashes.
Suspicion is a memory leak, here are detailed steps:
Run the fiddle, go to Profiles -> Take Heap Snapshot
Go to Timeline and start the capture. Enter some numbers into the cells for 30 seconds. Stop the capture.
We can se a constant increase in Heap size going from ~20MB to ~360MB.
To assure, go to Profiles -> Take Heap Snapshot.
The snapshot size is ~300MB.
What is Expected?
Normal operation after entering large set of numbers.
What is actually happening?
Memory keeps getting allocated and not being freed, which leads to application crash.
