0.11.b4 hierarchical menu glitch

[iNSiPiD]

There's a glitch displaying all the children of a group when the children themselves have children. Only the first child displays. When I click to expand this child, it then displays the other children at the same level ad nauseum.

i.e. Expand 7.1.1 in order to see 7.1.2 and 7.1.3; and then expand 7.1.3 to see 7.1.4 etc.

This continues to occur as children with children of their own are encountered.

Shouldn't it be that when you expand 7.1 you will see 7.1.1, 7.1.2, 7.1.3 and so on?

See before and after screenshots for better understanding.
