Top nav total width jumps if nothing is in "center"

[Jeitan]

I'm not sure if this is by design or not, but the whole bar appears to change widths on me if I don't have any icon set to "center". This happens on all of the SE sites I've checked (Code Review, Emacs, MSE, and Chinese Language) except SO. I'm on Windows 10, and I get this behavior both in the Firefox (56.0.2) and in Chrome (61.0.3163.100).

I am using the integrated site switcher and have set help to the left and everything else to the right. On SO, it looks like this:

But on MSE it looks like this:

If I move something (Achievements, for example) to the "center", it jumps to full width again:

Thank you for the report. I can easily duplicate the issue with version 1.0.1 of TNC. It has been fixed in the next version.

Given how obvious this is and the fact that I don't normally have anything displayed in the center location, I strongly suspect this is showing up now due to a change in the SE CSS. I find it difficult to believe that I wouldn't have seen it in my normal use of SE. I use a wider than SE-normal window, which would have made it even more obvious. However, it's already been fixed as a result of other changes in the next revision (i.e. I can't duplicate it in the development version).

Great! Thanks for pulling this together, it has definitely improved my SE experience after the new bar came out :D
