bug#52587: 29.0.50; Wrong block header/footer background in Org

["Rudolf Adamkovič via Bug reports for GNU Emacs, the Swiss army knife of text editors" <bug-gnu-emacs@gnu.org>]

I keep seeing buggy drawing in Org with Modus Themes.

Reproduction steps:

1. run 'emacs -Q'
2. type 'M-x load-theme'
3. type 'modus-operandi'
4. type 'C-x C-f'
5. type 'test.org'
6. type:

* foo
#+begin_quote
bar
#+end_quote
* baz

7. move point to 'foo'
8. type 'TAB'

Expected: headings with default (white) background

Actual: one heading has buggy (partially gray) background
