Full screen popup is not positioned properly after scroll the page

when using a dropdownlist with the allowFiltering="true" setting on a mobile device (iOS, Android) where the page is being scrolled, the popup is displayed in the wrong position (as shown in the attached images). The page will display correctly when not scrolled, but when scrolled down, the popup is incorrectly positioned. Additionally, I have included four images in the below sample, with the first one displaying the page in an unscrolled state, the second one showing the popup correctly displayed when opened from the state in the first image, the third one displaying the page being scrolled down, and the fourth one displaying the popup incorrectly positioned when opened from the state in the third image.

 Sample: TestSf_5a0543a5.rar

Replication Procedure: 

  • Run the sample in mobile mode
  • Scroll the page
  • And open the dropdownlist popup
  • You can see the issue

Current Behavior : popup is incorrectly positioned

Expected Behavior : popup should open in correct position even after scroll the page
