Some ampConfig settings are ignored in Portrait view

[abalmush]

I'm trying to set the amount of images in nav using:
ampConfigs: { navElementsCount: { forDesktop: 4, forDesktopFull: 4 } }
It works pretty well in Full view and standard desktop, but doesn't work on Portrait. I still see more than 4 images. I found out that portrait is missed in:

Viewer.prototype.getAmpConfigs

Is there any ways I can configure this without changing the code?
