Descriptions in grid column picker (list view checklist) do not go to two lines

[Blackbaud-TrevorBurch]

Expected behavior

I would expect the description in the grid's column picker to go to two lines or use ellipsis if they string is longer than what will fit to one line

Actual behavior

The description just runs off the side and the end is not visible

Steps to reproduce

1. Create a sky grid with the column picker with a column that has a very long description
2. Open the column picker
3. Observe

Plunker

This actually appears to be an issue for any list view checklist that has a very long description.

Looking at the styles for the list view checklist it appears that it should be putting ellipsis at the end of the description but that is not currently functioning
