Drag event disable when slider is load

Radzen Studio Blazor Server
1

Hi, I just discover a bug with the slider and the drag event.

Step to reproduce the problem :

  1. Go to the Radzen demo site: https://blazor.radzen.com/image
  2. In any page, try to drag something and you will see a little image preview or the text will be highlighted

  3. Then visit the slider demo page: https://blazor.radzen.com/slider
  4. Go back to the image page (or any page) and try to drag something or highlighted some text again. The drag event doesn't work. I try on edge beta and Google Chrome

Thanks and have a nice day!
