When the anchor element is changed, the Popover remains on the old one.

A basic example of the issue is using the Popover with a Grid: https://blazorrepl.telerik.com/cyuGvQPB37aekvo514.

On initial load, the Popover is properly attached to the span elements in the Grid cells. If I filter, however, the elements are disposed and re-initialized - after that, the Popover is not attached to the new elements even though they have the same class used as a target selector.

The AnchorSelector parameter of the Popover should support runtime changing. Currently, to change the parameter value, the app must recreate the component by removing it temporarily from the page:
