I recently changed how some of our variables are passed around, simplifying things and making sure our body and html elements inherit from a single place instead of a super circuitous route. Something may have shifted slightly.
This got fixed this afternoon. Thanks for pointing it out! In our effort to improve our frontend so things like this are less likely to slip through the cracks, something like this slipped through the cracks. THE IRONY!
The reputation update in the top bar is 'powered' by the same websocket on all pages. No matter where you are, you will always receive the same updates. It might take a few seconds for the +2 to register, so if you navigate away from the page too soon, you'll miss it. But AFAIK this has always been the case and is definitely status-bydesign.
The fix is quite simple:
When I change the height property of .posts-navigation in the CSS from 10 to 15, as in below screenshot
The bottom of the arrow alligns with the bottom of the word "Previous", the text is however now slightly smaller in height then the arrow is.
