Simulation include directive

I have simulation schematic that use to use .include "xyz\bcs\aaa.cir" in a text object. It work fine in KiCad4. In KiCad5, it generate net list with double quoted twice. This cause ngspice sim no longer understand it. And I had to remove my double quote in the text object to have it work. It this a intended new behavior? or should I report as bug?

Well - I just add the bug report anyway: https://bugs.launchpad.net/kicad/+bug/1786559
