xdebug doesn`t see what is inside \Ds\Map

[KonstantinKuklin]

$abs = new \Ds\Map([1,2,3]);
xdebug_break();

xdebug shows 'can not get property' inside the $abs in PHPStorm
But with \Ds\Vector xdebug works correct, that is why I create issue here.

Can you please give me a way to reproduce this without using PHPStorm? Because without PHPStorm I'm not seeing "can not get property".

Using PHP 7.0.9, XDebug 2.5.0
