Feature Request
Grid popup edit window can be dragged outside the viewport (no ContainmentSelector on GridPopupEditSettings)
Product: Telerik UI for Blazor 14.0.0, .NET 10, Blazor Server
In UI for Blazor 14.0.0 the Grid popup edit window can be dragged past the right and bottom edges of the viewport. When that happens the title bar is out of reach, so the user cannot drag the window back or reach its buttons. Only dragging past the top and left edges is prevented.
Steps to reproduce:
1. A Grid with EditMode="GridEditMode.Popup" and GridPopupEditSettings (Title, Width, Class).
2. Open the edit popup for a row.
3. Drag the window by its title bar past the right or bottom edge of the browser window.
4. The window disappears out of view and cannot be dragged back.
Expected: the title bar of the popup window stays within the viewport, or GridPopupEditSettings exposes ContainmentSelector (and preferably Draggable) like TelerikWindow does.
We now use a JavaScript workaround that depends on internal parts of telerik-blazor.js (TelerikBlazor._instances and the window's setPosition), and that will break on future updates. Is there a supported way to constrain the popup edit window, or can this be added?
