Steps to reproduce the bug

Click the 【array】button.

Expected behavior

I'm sure that "mutation.events.key" indicate the name of the state. By clicking the 【array】button, the "array" state is updated. Thus "mutation.events.key" must be "array".

Actual behavior

"mutation.events.key" is "0".

When the state is a String, "mutation.events.key" indicates the name of the state without issue.

Additional information

No response

This is expected and it comes from vue core. The actual key changing is the index of the pushed value
