ConvertFrom-Json: comments in top-level arrays are parsed incorrectly (but also are not errors)

According to #7436 ConvertFrom-Json should support "JSONC"-style comments present in JSON objects without issue.

However this doesn't seem to work if the comments are in a "top level" array - instead the comments are interpreted as strings-elements within the array.

Steps to reproduce

ConvertFrom-Json -NoEnumerate "[`n// foo`n 100, `n /* bar */`n 200]" | ConvertTo-Json -Compress

Expected behavior

Either an error (due to comments not being supported) or:
