DevTools does not open as child popup window.

Is there an existing issue for this?

[X] I have searched both open/closed issues, no issue already exists.

CefSharp Version

Operating System

Windows 10

Architecture

x64

.Net Version

Implementation

WinForms

Reproduction Steps

Showing DevTools on the MinimalExample using the code below does not work as it did previously.

        private void ShowDevToolsMenuItemClick(object sender, EventArgs e)
        {
            var host = browser.GetBrowserHost();
            var windowInfo = new WindowInfo();
            windowInfo.SetAsPopup(host.GetWindowHandle(), "DevTools");
            browser.ShowDevTools(windowInfo);

        }

In version 128.4.90, the code above shows DevTools on top of the browser control, covering up large part of its top-left are.

In a previous version (121.3.70), the same code above shows DevTools as a child popup window of the browser.

Expected behavior

DevTools should show up as a popup window.

Actual behavior

DevTools is rendered on top of the browser control, covering up a large part of its top-left area.

Regression?

Yes. This works in v121.3.70.
