In a freestyle job configuration, if I click advanced, and set a custom workspace (checkbox + textarea), the next time I open the config these elements are duplicated higher up on the panel, with the checkbox checked, but with a blank textarea. The original elements are correctly configured, but hidden in advanced.

This is very confusing, because it looks like no custom workspace is set. If I enter a directory in the top set of elements, and click apply, 2 customWorkspaces are posted, and the second hidden one always takes precedence.
