Change text selection color in edit mode

Hi guys! I am trying to set custom CSS that fit my workflow and taste. I could not find the CSS selector for text selection in edit mode. In preview mode it is simply --text-selector, but it does not affect the other one. It is annoying, because the default selection color is very similar to my --text-normal color, which becomes difficult to read. Thanks for your help!

As far as I can see the right attribute is --text-selection.
