Open an article with a table, for example:
Accidents with ships from 1951 to 1960.
Set the color theme to dark (independent from the system).
Look at the table, the dark theme makes the backgrounds of the rows alternate dark and bright, but not the font color, so you can not read the text in bright rows.

OS: LineageOS 19, which is Android 12.
