When having indexed embedded entities, field name can be quite long, for example "provider.address.city.country.name" and the column which displays field name in Overview tab has a limit on its width.

Reproduce the issue in Luke 8.11.2 using an indexed embedded entity with a long field name, then inspect the Overview tab's field-name column and its resize behavior. Done means the column can be resized far enough to display long names such as "provider.address.city.country.name".
