Dark Mode possible bug

Under Dark mode, if a user wants their cards to show up as they do under light mode, but still have the interface be dark they add filters to the CSS to invert the dark colors. This seems to work on the iOS devices, but on the Desktop, the pasted images still look like they do under Dark mode.

This is also true for the preview under browse.

The CSS I am using is invert the colors:

background-color: Ivory;
-webkit-filter: invert(1);
filter: invert(1);

If you want a dark interface but black on white text/content, you can just adjust the foreground and background colours?
