I believe this is expected and it's not a bug.

When the list of parameters breaks on multiple lines, the formatter always adds a leading comma for the last parameter. In this case, the last is also the first.

However, the es5 trialing comma is definitely buggy, and we should fix it (with low priority I suppose)

Interestingly, Prettier has the same issue.

It seems they behave differently when setting trailing_comma to es5. playground
