[Minor bug] Linebreaks occasionally disappear

Sometimes they disappear from posts and even from the main page. Refresh doesn't consistently help. Closing the tab and opening it again from a link does fix it. Not sure what is happening to cause this, but it only caught my eye today. Note: only some linebrakes disappear, while the rest remain. So it's not the issue of the line itself.

What browser are you using? I am guessing that opening in another browser causes the linebreaks to reappear if they do when you open from a link, but have you seen the issue in more than one browser?

I'd also be curious if it might be a caching issue--if holding down Cntrl+Shift and reloading rather than re-opening the page would make them reappear. (Just a random thought, probably not the solution).

Out of curiosity, is it consistent which ones disappear and which don't?
On mobile for me, the linebreaks in your post have different widths: the one below 1 and the one below 4 are thinner than the rest. If it's them which disappear, then maybe these visual issues might have something in common?

It is consistent, indeed, but not across different browsers. I noticed that different browsers trigger different lines.
