Text in code block unreadable when printed

[Rijswijker]

Describe the bug
When a page is printed the text in the code block section is almost unreadable due shadow.

To Reproduce
Put a text in a code block and click on the printer icon and print to paper or pdf

Expected behavior
Black or color coded text without shadow

Screenshots

CSS override does not help, the override is ignored
