Steps to reproduce
Adding undefined to event handler with modifier in for loop will cause error. Minimal reproduction demo is given in link above.
There is an almost same issue before #9865, which has been fixed.
While in for loop, this issue still exists and will cause failure.
What is expected?
Like issue in #9865, vue should ignore empty event handler with modifier in for loop
What is actually happening?
sfc fails to render if adding undefined handler to event with modifier in loop
