Oops. You are indeed right. I was trying to convert the report from   
https://orgmode.org/list/wxaUFiqi8BmIPv8pcYRVHAFa0hTzM35roQxpVVRkgddjRkesPGX1kVBL3G0fr42FonlRq5FNjapV8RiovXV-RGEDehXn-cmIebf4HWBhzIQ=@protonmail.com
to something simpler.

However, Emacs indeed does the fontification correctly here. The origin
of the problem in the linked message has something to do with htmlize
package, not directly with Emacs.

Please ignore this reproducer.

Best,
Ihor
