update January 18, 2019
Yesterday or so I first noticed this issue seemed to have been solved (possibly network-wide). It my have been so for weeks.
I don't know where to link to, if that issue has been discussed elsewhere on the network. With this information added, I guess that question can be closed. Ah no sorry, I confused with issue trackers. So if an answer linking to suitable network resources is provided I shall check its correctness and validity and validate the answer (despite my incomptence in all things CSS and JavaScript).
Screenshot with added red line (which I tried to make vertical):
The left alignment is deficient.
Is it a site problem?
As reported in comments, (initially triggered by this additional image:)
at least the amount of additional indentation seems to be decided by the styling of the number of answers: the shortest is "1 answer" (whether it has been accepted or not), then "0 answers" is wider although unframed, and "2 (or more) answers" is even wider due to its framing (be it filled or not).
On https://tex.stackexchange.com/questions/
the layout is vertical, and I perceive no raggedness, did not check thoroughly though. The horizontal layout of https://tex.stackexchange.com/
is an ingredient of this issue.
As pointed out in comment by @samcarter, this is network-wide problem as one can see at meta.stackexchange.com
