Can't move Emby when installed as an app in Edge

[IdeasMan 13]

I'm not sure why this is only a recent thing but after a recent update in Microsoft Edge, I've noticed it's no longer possible to move the Emby window when you "install" Emby as an app in Edge. This is because Edge is no longer displaying the title bar for the window.

From what I've gleamed, it looks like the app-region style is missing from the div where the custom title region has been defined.

It looks like you've employed the Display content in the title bar area using Window Controls Overlay stuff because the window's title bar is now gone. This leaves a few pixels to the left of the ellipses where you can drag the window using the window's control buttons overlay. If you attempt to move the window by clicking anywhere the title bar should be, you'll notice you can't.

If you inspect the page using DevTools and select the div whose container-name is appheader, you'll notice the app-region style is set to none. If you explicitly add this style to the div with the value of drag, you can now move the window around by clicking the pseudo header.

The only other way to move the window is to use an old Windows 3.11 trick of using the Move command from the window's system menu.

Emby Server: v4.9.5.0.

Reproduction steps:

1. Navigate to your Emby server in Edge.
2. Click the ellipses > Move Tools > Apps > Install <ServerName>.
3. Click Install.
4. Emby will reload the tab into its own window as an "app".
5. Attempt to move the window using the title region where the title bar should be in the window. Notice you can't.
6. Open DevTools.
7. Locate the div whose class attribute contains headerTop.
8. Edit the style attribute to include app-region: drag;
9. Attempt to move the window using the title region where the title bar should be. You can now move it.
