Issue Summary

When Mapping attributes in Import Screen, for the last attribute mapping Destination attribute drop down is too small and displays till the width of the current mapping screen. 

Due to this we cannot select the last attribute as it never appears in drop down.

Steps to Reproduce

1. Create a Asset Import > Create Mapping.
2. Add a new row > Try to select destination attribute > Drop Down is too small and we cannot see the last attribute.

Expected Results

All available attributes should show in the drop down with visible scroll bar or long list.

Actual Results

For last attribute mapping, drop down values not showing complete list.

Workaround

As a workaround we can type in the attribute name and it will appear for selection.
