Description

Paging on Hosts page seems to work randomly on the 2K-node cluster.

• Sometimes clicking on back / next to page does nothing.
• Sometimes it refreshes after delay (long after the overlay is removed).
• Sometimes the page number and the host content gets out of sync.
• User-specified page size is not respected.
• Sometimes, hitting Back from Host Details page shows only the host that was visited, but none of the other hosts that were showing before going to Host Details page, then after a while, other hosts show up.
• Looks like overlay is not displayed, even if UI is still updating or waiting on data.
• Also, this random behavior might be caused (or partly caused) by JS errors. I see errors like "Uncaught Error: <DS.StateManager:ember21797> could not respond to event didChangeData in state rootState.loaded.updated.uncommitted."
