- The logic for setting the 'fragment' property might not correctly handle cases where both 'parsed.fragment' and 'request.fragment' are falsy. Consider using 'parsed.fragment ?? request.fragment' to handle these cases correctly.

Improves performance all-up (especially in
ParsePlugin,JoinRequestPlugin,JoinRequestPartPlugin) by ensuring that theResolveRequestobject always has a constant shape.Note that this is technically a breaking change to plugin authors, if they took a dependency on the ability to attach arbitrary properties to the
