cannot drag vertically when container's height get very large

[adajoy]

environment: IE11 WIN10 1903

this issue only happen with IE
this maybe a problem with getComputedStyle() will return negative value in IE when value get large, like 300000px.

codepen doesn't support ie, you can open the pen with other browsers, copy the code and run it locally to reproduce it
