Regression in parsing of trailing trivia for fields in a punctuated struct

[JohnnyMorganz]

Seeing a stylua regression for the following test case in v1.1.0

-- https://github.com/JohnnyMorganz/StyLua/issues/547
local too = {
	x,		-- string
	y		-- string
}

Before, the comments used to be parsed as trailing trivia for the comma after x, and for the y field respectively. Now the comments get parsed as leading trivia for y and the closing brace } respectively.

Blocks JohnnyMorganz/StyLua#854

The problem occurs because the whitespace before the comment is from tab characters, not spaces
