On the vote-total popup, the leading +
or -
is suppressed once the total hits three digits:
This happens in both the 🟢 upvotes on the top and on the 🔴 downvotes on the bottom.
This has been observed before back in 2010, but that bug report was mysteriously marked status-bydesign despite clear evidence to the contrary being presented. The reason that does not address this problem adequately is because since it was asked fourteen years ago, the behavior has changed, and for the worse.
As I mentioned in comments,
notice how when you open up the currently −132
score here, the loss of the sign makes its column a wee bit more narrow and causes the text column of the question proper to suddenly reflow as it finds a few more pixels to occupy than it had before you did the popup.
Isn't that just bizarre? They already paid the price before the popup, did the whole layout, and by snatching back the sign at popup time they make the main column reflow. Really freaky.
Now that we have four- and even five-digit scores, you’re obviously spilling into the third position and beyond already. It doesn’t only print the last three digits! So there seems no sound reason remaining to deliberately suppress the sign any longer, if there ever was.
