Add pool row IDs for icons in new UI
Go to Storage / Pools. Right click on icons (locks and gears). Each should reveal an id (either on the icon or on its containing div that contains the name of the pool, making it a unique identifier.
Pools formerly had gear icons with elment IDs for a pool named "pool1" like "table_actions_menu_button__name_pool1".
The significant part of these IDs, the pool name, is now missing. They are "table_actions_menu_button___".
The ID of the entire row expansion panel is still present ("expansionpanel_zfs_pool1"), but that is the only other identifier with a unique pool name.
Expansion panels are not expanded by default unless only a single pool is present. When expanded, multiple gear icons can be present, so locating the gear icon for a particular pool is difficult.
