Expand / collapse of token sets causes weird UI issues

[six7]

When your token sets share the name with token folders, and you expand/collapse token folders, the UI will act weird.

To reproduce:

• Create a set called core/foo
• Another one called light/foo
• Another one called core
• Another one called light
