Looking closer I see a couple of JavaScript errors when I load this or another form which now exhibits the same behavior. These extra changes are not mine, so I am working with my colleague to get the errors resolved.

Hopefully they are the reason for this behavior.

UPDATE :( The JavaScript errors are gone now, but the problem remains with that new ng-grid version.
