[OPEN-1152] TreeGrid with single top-level node doesn't display properly in IE7...
...but is good in IE8.
In IE7, even though I've set the first node to 'expanded', the children are not shown. The twistie indiciates that we've children, but these rows are not shown.
The children reappear if you close the twistie, and then reopen.
In IE8, you can see the expected behaviour.
This appears to only be a problem for data in which there's only one top-level node.
Has anyone seen this type of behaviour before?
