Problem

The "Edit String Expression" dialog does not work for large tables and more than a few options.

How to reproduce

1. Load the attached file Example.dmn in Camunda Modeler
2. "Exit advanced mode", if necessary
3. Scroll down to rule #28
4. Left-click input column Assetklasse in line #28
5. Try to scroll down to the last option in dialog "Edit String Expression" -> does not work with mouse or keyboard (see screenshot)

Expected behavior

All input options are reachable.

Workaround

Enter advanced mode and edit value directly.
