backend form fields not readable for systems with dark themes, no text colour defined

[cocoknight5]

Most fields in the backend don't have background color and text color defined, leaving it to the system to decide the colors.

The title fields for pages and posts however have the background color set to white, but the text color is set by the system configuration. For people who are using a dark theme on their system, with white or almost white text, this means that the title field will display white text on white background, making the text unreadable.

There are two possible solutions for this: Either remove the background color or specifically define a text color.

It looks like this issue's gotten worse, since 2.9 I believe. Most fields' text in the backend are now not visible for people using white font colour on their system theme. In fact, as far as I can tell the rich text editor's field is the only one to show black text on white background instead of white text on white background. So there's probably a general CSS rule somewhere that defines the background of all form fields. There, a definition for the text colour should be added.
