DropDownList pupup is in the wrong position on Windows 10 touchscreen laptop.

This problem is occurs on a Windows 10 touchscreen laptop.
There is a dropDownList on a page.

Step:
1.After the page is initialized,click the dropDownList using the touchscreen,and the menu pops up.
2.Use two fingers to zoom in the page,and move the dropDownList using the touchscreen.
3.Click the dropDownList using the touchscreen,and the popup is in the wrong position.

After step 2,the origin position has been changed,dojo should have recalculated the origin position,but in fact it didn’t do that,so that there is a origin offset.
I can't show real information in our product,but I made a picture to explain more clearly.
