How to turn off auto inserting comma

Could you please help to find how to turn off auto inserting a comma after array item for instance

example (C#) var array = new [] {1 , 2, };

rider automatically insert a comma, how to turn it off? I've checked the Typing assistant, but no luck.  I don't even understand how this feature could be useful, the last comma is useless and rider suggest to remove it, so at first, Rider added and then suggest to remove. what's the point? looks like a bug
