How can I change drag background-color ?

I want to change drag back-ground-color

i've changed theme selection color, but it doesnt work

`

import ReactCodeMirror from "@uiw/react-codemirror";
import {
loadLanguage,
langNames,
langs,
} from "@uiw/codemirror-extensions-langs";
import classes from "./EditorBox.module.css";
import createTheme from "@uiw/codemirror-themes";
import { markdown, markdownLanguage } from "@codemirror/lang-markdown";
import { languages } from "@codemirror/language-data";
import { EditorView } from "@codemirror/view";
import { javascript } from "@codemirror/lang-javascript";

type ContentType = {
content: string;
contentHandler: () => void;
};

const myTheme = createTheme({
theme: "dark",
settings: {
background: "#121212",
foreground: "#4D4D4C",
caret: "#AEAFAD",
selection: "#000",
selectionMatch: "#000",
gutterBackground: "#FFFFFF",
gutterForeground: "#4D4D4C",
gutterBorder: "#ddd",
gutterActiveForeground: "",
lineHighlight: "#EFEFEF",
},
styles: [],
});

loadLanguage("tsx");

export default function EditorBox({ content, contentHandler }: ContentType) {
return (
<>

<ReactCodeMirror
theme={myTheme}
value={content}
onChange={contentHandler}
height="100vh"
basicSetup={{
foldGutter: false,
lineNumbers: false,
highlightActiveLine: false,
}}
extensions={[
markdown({ base: markdownLanguage, codeLanguages: languages }),
EditorView.lineWrapping,
javascript({ jsx: true }),
]}
/>

</>
);
}

`

Start with the ReactCodeMirror theme configuration shown in the issue and the imported EditorBox.module.css file, then inspect how drag styling is applied. Verify the result by dragging text in the editor and confirming the background color changes as requested.
