Comment (by swissspidy):

 @michael.bucklin Thanks for the details! I think you explained well
 enough, I've just digressed while investigating the cause.

 > This redirect is what is causing the URL parameters to change, as PHP
 sees all periods as underscores and can't re-add them in the original
 form.

 There were some changes to canonical redirects, see #21602, #35344, #35847
 for example.

 I don't think the redirect is not the problem here. It only brings the
 issue with the replaced periods to light, which apparently is being done
 by WordPress at some point, not PHP itself. At least that's what I saw
 when I had a second look.

 For the buggy redirect, I recommend you to report it in one of the tickets
 I mentioned.
