Selected text is not hightlighted

[boskokg]

When I select some text, visually selected text is not hightlighted.
Note:I can copy/paste the selected text.
Note2: I am reproducing the same in the provided example https://rapidocweb.com/examples/example1.html

I have not found that someone reported this.

Experiencing this as well. Fixed by setting the --selection-bg and --selection-fg variables in my css.

:root {
  --selection-bg: #444;
  --selection-fg: #eee;
}
