Comment (by steevithak):

 I can get you the additional data tonight when I get home from work. In
 the meantime, my guess is perhaps the problem doesn't show for posts
 created on 5.3? Maybe it uses the same method to generate the static
 permalinks as it does to build the dynamic link refs? Maybe try creating
 posts on an earlier version and then upgrade to 5.3 and see if the
 dynamically built links change relative to the static article permalinks?
 (I don't know the details of how the code works in that respect so just
 making wild guesses!)

 FWIW, the link above is exhibiting the described problem now (around
 08:15am central time in Dallas, TX). Not sure what time zone my server is
 in. It's a cloud vm, so probably UTC. I also have the archive list widget
 on my home page, which makes links that only include the year and month.
 In the archive link for July 2018, you can see the example post from
 above. But if you click the title on the post page to get directly to the
 post page, you get a 404 (which my theme redirects to the index page).

 I have hundreds of posts and only currently see this issue on a small
 number, so maybe the post has to made within the span of time between
 midnight in the two time zones to exhibit the problem? Or maybe it only
 manifests when the original post time is near midnight in the whatever
 zone WP 5.3 is using - so only 1/12 of my posts would shot the issue at
 any given time? I post at very random times, so more likely to hit a few
 of mine than someone who posts at the same time each day I guess.
