Alterou-se a marcação de destaque em blocos de código no tema escuro do WCAG?

Hi, I am noticing that WCAG Dark theme is not highlighting code between codeblocks (anymore for some reason). I have been using WCAG Dark theme on the openSUSE forums for over a year with no problems.

I am aware of this font WCAG change :< Codeblock text seems smaller

I really thought there used to be some slight highlighting when codeblocks are used with the WCAG Dark theme.

Has this possibly been changed upstream?
