Everyone has their own set of gripes about the redesigned top bar, but they're all neglecting the most egregious issue:
Look* at that inconsistent positioning**! The icons are shifted whole pixels because the computed font size for the top bar is inconsistent across the network. On some sites, such as Meta, the font size ends up being 13px, while on others like Gaming it's a meager 12px.
Admittedly I doubt most people would notice, but for users like me who have multiple sites open in different tabs and switch between them, it's something you can't unsee after it's been seen. As it's easily fixed by just setting an explicit font size for
.topbar .network-items, could that be done for the sake of Great Justice?
*The top section is the two examples overlayed
**There's also inconsistent colouring, but this is currently by-designer.
