All (well, most of) the icons for sites in my Hot Network Questions sidebar are misaligned or otherwise broken:
I'm seeing this on all of my devices (MacBook, iMac, iPhone), which are all using Safari. It curiously does not appear to happen on meta SE, but it does happen on every other site I've tried. It's been happening since at least last night.
I realize this issue has been reported before
but all of those issues are old (from fall 2015) and reported as fixed. Has the issue re-appeared, or am I doing something dumb on my end?
