Incorrect comment formatting when formatting Member Expressions with trailing comments

[AllanJeremy]

Summary

• Stylua version : 0.14.1.
• Description: Formatting a single member expression with trailing comments fails

Details

When formatting code that contains member expressions with trailing CommentLine comments, if we have a single member expression, then the member expression is pulled into the previous line thus producing invalid lua (and commenting out the member expression).

Steps to reproduce

Unformatted code

local foo = bar -- comment after bar
        .fizz -- comment after fizz

Formatted code ❌

local foo = bar -- comment after bar.fizz -- comment after fizz

Expected output

local foo = bar -- comment after bar
        .fizz -- comment after fizz

Bonus

Code that works

When we have multiple member expressions, then the comment positions are preserved

Input code

local foo = bar -- comment after bar
        .fizz -- comment after fizz
        .buzz

Formatted code ✅

local foo = bar -- comment after bar
        .fizz -- comment after fizz
        .buzz
