Bug description:isset triggers fatal error when accessing object as array

Description:
------------
This worked for quite a long time, but stopped working recently, I suspect
due to 
#53971 being fixed. I think isset should never trigger any error

Test script:
---------------
$x = new stdClass;
$x->a = 'b';
var_dump(isset($x['a']));

Expected result:
----------------
false

Actual result:
--------------
PHP Fatal error:  Cannot use object of type stdClass as array in php shell
code 
on line 1
