Steps to reproduce
1. Scroll down to the bottom of the page
2. Open combobox dropdown
3. Select any value (this works as expected)
4. Open dropdown again
Document should not scrollback to the top
Document scrolls back to the top and user need to scroll back down to the botton to access the combobox component.
Note: In modal window the document scrolls back to the top in step 2 itself i.e. when first time dropdown is opened.
