-// When there are multiple Prettier plugins, there can be conflicts when both try to use the same language parser.
-// This occurs because when a language parser is re-assigned, handlers from previous plugins get lost.
-// Below we merge the babel parser handling of both plugins to avoid overwriting each other.
-// We need this hack until Prettier does something about it.
