Comment (by jokanane):

 I installed fresh 5.7.2 and 5.8 side-by-side, no other plugins than what
 the core installs, default theme 2021.

 I then uploaded and set the site logo file in both identically and set..:
 {{{
 <?php var_dump(get_theme_mod('custom_logo')); ?>
 }}}
 ... in header.php.

 5.7.2 returns int(10) and 5.8 string(2) "10". This alone is surprising and
 makes one wonder if there's another regression around here that's causing
 the problems we're seeing.

 @eqwmo if you know how, do the var_dump() given above with your site
 having 5.7.2 and then with 5.8. I bet my money that you'll see an integer
 with 5.7.2 and an array with 5.8. That will throw off the code that is set
 to render the image.
