Fixed
- All themes except the UniFi family — Expanding a nav section in an LXC or VM (Firewall, and any other section with children) no longer makes its subsections invisible. The selected item's on-accent text color was set with a descendant selector,
.x-treelist-item-selected .x-treelist-item-text, but ExtJS nests child items inside the selected<li>, so children were painted the same dark color as the panel background. Scoped to the item's own row,.x-treelist-item-selected > .x-treelist-row .x-treelist-item-text. Affects LXC and VM alike. Issue #54
