Steps to reproduce

1. Edit an asset, and reduce the width of the browser window until responsive design modifies the width of the frame.
2. The FocalPointField gets cropped making it unusable (point not settable on the right-hand side of the asset)

Expected results

The FocalPointField should not be affected by responsive design.
A.) Assign the field a fixed width (i.e. the asset's width) instead of a relative width (i.e. width:100%)
B.) Show the overflow using scroll bars. 

Actual results

The asset gets cropped.

Workaround

If possible, enlarge the browser window.
Note that this may not work on low. res. displays, however (issue reported by Bike24).
