There is no problem with the version of idea from 2023.1 to 2024.3. The code is as follows:

class ChatBrowser(private val project: Project) : JBCefBrowser(
  createBuilder()
    .setOffScreenRendering(
      when {
        SystemInfo.isWindows -> false
        SystemInfo.isMac -> false
        SystemInfo.isLinux -> true
        else -> false
      }
    )
    .setEnableOpenDevToolsMenuItem(true)
) 

loadHTML(htmlContent)

private fun jsLoadChatPanel() {
    val config = currentConfig ?: return
    val chatUrl = "${config.endpoint}/chat?client=intellij"
    val script = "loadChatPanel('$chatUrl')"
    executeJs(script)
  }

private fun loadHtmlContent(script: String) = """
      <!DOCTYPE html>
      <html lang="en">

          iframe {

          function reload() {
            // handleReload is a function injected by the client
            handleReload();
          }
      
          function showMessage(message) {
            const messageDiv = document.getElementById("message");
            messageDiv.style.cssText = "display: " + (message ? "flex" : "none") + ";";

            document.documentElement.className = theme;
            document.documentElement.style.cssText = css;
          }
      
          window.addEventListener("focus", (event) => {
            const chat = getChatPanel();
            if (chat.style.cssText == "display: block;") {
              setTimeout(() => {
                chat.contentWindow.focus();
              }, 1);
            }
          });
        </script>
      </body>
      
      </html>
    """.trimIndent().trimStart()
  }

By calling loadChatPanel to load the webpage URL into an iframe and then displaying it, the plugin in idea 2025.1 does not support Chinese input and scrollbars. This issue did not exist in previous versions. What should I do? Thank you
