Navbar Fluid button turns blue when DESELECTED (opposite normal behavior)

This is probably the most trivial little bug ever spotted in BSS, but I just noticed that when the Navbar "Fluid" button is "off" (deselected) the word Fluid is highlighted in blue, which typically indicates a button has been selected. When you turn the Fluid button "on", the word Fluid turns gray (typically indicating the button is deselected.)

I know, totally trivial, but I did see, so I felt compelled to report it.

I have since been informed by the devs that this is normal behavior, so please ignore this post. Bootstrap makes the Navbar fluid by default, so turning off fluidity is actually changing the normal status.
