Console error saving code

[Alisonispig]

There is a strange error that does not affect the operation, but it is very uncomfortable. It appears after updating the latest version, not every time. If you don't repeat it at the first time, please pay attention

I can add a security check, but how do you reproduce this error exactly? On which browser?
