Parse error when adding def to trailing-comma import list

[georgefst]

import Prelude (
  Bool,
 )

x = not

Running the code action to add not results in:

import Prelude (
  Bool,, not
 )

x = not

HEAD (445192e) with GHC 9.2.3. I'm pretty sure this is a regression since the last release.

Duplicate of #2958? I'm trying to fix it in #3035.
