Problems with moving comments when automatically moving child arg to last parameter position of widget constructor

[lukehutch]

I get The 'child' argument should be last in widget constructor invocations for this code:

Issue 1: Hitting Save moves child to the end, as expected. But the comment is lost:

Issue 2: If the comment is on a different line, it moves with the line (this is correct so far):

However, if there are only 2 lines, weirdly the parameters switch without moving the comment!
