Bug [RS3] InterfaceWindows

Whenever I call

Code (Text):

1. if(InterfaceWindows.getEquipment().isOpen()) {
2.  
3. } else {
4.     InterfaceWindows.getEquipment().open();
5. }
6.  

And my layout looks like this:

It returns false, so it wants to open the equipment tab. Instead of just clicking on the icon shown in picture above, it moves all the way to the navigation bar, and opens the equipment tab that way.

Expected result:
Gyazo - eeb372d61788d204e1a21ddce17c88dd.gif

This does not only apply to getEquipment, but also getInventory. I assume it applies to the following as well:
getMagic()
getPrayer()
getSkills()

 

@SlashnHax any update on this?
