Can't select transform tools when the toolbox docker is widened.

Reproducible: Always

Steps to Reproduce:
1.widen the toolbox docker until the transform tools appear in the same "row" as some of the paint tools:

Freehand Path, Dynamic Brush, Multibrush | Crop, Move, Transform, MEasure

Actual Results:  
Can no longer select any of the transform tools

Expected Results:  
Should be able to select them, regardless of size/shape of docker

If I continue to expand the docker so that the tools appear like this on one row:

Transform Tools | Color Tools (Fill/Picker/Gradient)

Then the transform tools become selectable again.
