CSV Data Set Config fields width increases

[asfimport]

chowdhurynahid (Bug 65878): When one of the CSV Data Set Config has long list of variable names, the other one shows same field width.

Recreation Steps:

1. Add 2 CSV Data Set Config
2. In one of the config put around 100 variable names and save
3. Click on the other one.

Expected: The second blank config fields should be of default width.

Actual: The second blank config fields are of same width of the first file.
