[Saikrishna Arcot <saiarcot895@…>]

What steps will reproduce the problem?

1. Zoom in into the Dallas North Tollway.
2. Select a road.
3. Scroll down the properties.

Note that I didn't paste anything or try to paste anything.

What is the expected result?
All properties are visible.

What happens instead?
A bug window shows up. Properties are still visible, though

possible.
