Hi All,
I have Oracle APEX 21.2.0 installed (upgraded from APEX 20.1) on a Oracle 18c XE DB.
After the upgrade, I've noticed that Interactive Grids, multicolumn Popup LOVs etc have a white background which makes them impossible to read when the application is using a Dark theme.
See the screenshot below.

If I switch the theme to Vita, they are visible properly.
It appears that the background colour is "fixed" to white but other colours like the region and text colours are changing depending on the theme.
So when the theme is set to Dark, the text becomes white which on the fixed white background becomes impossible to read.
Is there any fix available for this? Maybe custom CSS to force the background colour to change but that would mean we have to get the colour to match.
