While visiting this user's profile page, I encountered a UI bug.
Here's a screenshot:
As you can see, the text provided in the profile didn't wrap itself in the center, instead if pushed the right div or whatever (I am not that expert with html/css).
I am using Chrome Version 69.0.3497.100 (Official Build) (64-bit), Windows 7.
Note that by visiting his other SE profile page, this bug didn't appear.
