Another case where comments get formatted away

[fhammerschmidt]

Consider this example:

  (
    incidents
    ->Belt.Array.keep(({status}) => status === #OPEN)
    // This comment will vanish 
    ->Belt.SortArray.stableSortBy((a, b) =>
      compare(a.createdTime, b.createdTime)
    )
  )[0]

The comment is removed after formatting.

Simpler example:

let _ = (
  a // This comment will vanish 
  )[0]

This does a little bit in that direction: #5947

Helps with normal comments, but does not yet handle the line comment in the example.
Perhaps @mununki has some ideas?

Actually, it works reasonably well. I had overlooked the output to the original example.
