[bug] Deserialize breaks ctype inheritance

I've sent it to Lassosoft already, but thought the list archives might benefit from a 'heads-up' on a bug that bit me this afternoon involving inheritance, custom types and overloading onDeserialise (it's a ctype that's stored in a session variable, hence the deserialise).

When a ctype is deserialised into a var it seems to break the parent/child inheritance 'context' of the ctype. This means that the child type's member tags that should overload the parent's member tags are effectively unavailable.

Test case below.

<?LassoScript

define_type('type1');

        local( 'msgs' = array );

        define_tag('oncreate');
                self->whoami;
        /define_tag;

        define_tag('whoami');
                self->'msgs'->insert( 'This is a ' self->type );
        /define_tag;

        define_tag('membertag');
                self->'msgs'->insert('type1->membertag');
        /define_tag;
       
        define_tag('ondeserialize');
                self->'msgs'->insert('type1->ondeserialize');
                self->membertag;
                self->whoami;
        /define_tag;
       
/define_type;
       
define_type( 'type2','type1' );

        define_tag('membertag');
                self->'msgs'->insert('type2->membertag');
        /define_tag;

/define_type;

var( 'type2_normal' = type2 );

var('type2_deserialised')->deserialize( $type2_normal->serialize );
$type2_normal->ondeserialize;

encode_break( '$type2_normal:\n' + $type2_normal->'msgs'->join('\n') );

'<br />' * 2 ;

encode_break( '$type2_deserialised:\n' + $type2_deserialised->'msgs'->join('\n') );

/*

On Lasso 8.5.6 this returns:

$type2_normal:
This is a type2
type1->ondeserialize
type2->membertag
This is a type2

$type2_deserialised:
This is a type2
type1->ondeserialize
type1->membertag
This is a type1
