dropzone target fails if scrollable

[mohs8421]

If the dropzone is within a scrollable container, the scroll-offset is not respected. For example, if you have a list of 5 dropzones within a container that displays the first 3 on one screen. If you now drag something into the 5th. dropzone, it will end in the 3rd dropzone, as the offset value is wrong. This was first recognized in version 1.7.1_beta1, but it has not been fixed until 1.9.0

Noticed similar issue if browser zoom is increased to say 125%, then the dropzone target fails (wrong offset).
