I have a property called Backdrop that is bound to ShowBackdrop property on SfSidebar component. If Backdrop property is set to true and then changed to false while the sidebar is opened the backdrop remains. It remains visible even if the sidebar is closed. This can be repeated if sidebar is closed and reopened. Backdrop is then being created multiple times.
In my use case I change the Backdrop property via SfMediaQuery event - in smaller screen resolutions (on mobile devices) the backdrop is displayed and in desktop mode it should not be visible. The problem then occurs when resizing browser window.
I have included a demo and a video sample of this scenario (I have excluded the SfMediaQuery component to make it simple, Backdrop property is changed via checkbox).
