Inconsistent save states for fabric/subnet/vlan/space editing

[David Lawson]

When editing details of fabrics, subnets, spaces and vlans, the save condition for edits is inconsistent. Changes to spaces and VLANs take effect immediately on the text field losing focus, whereas subnets and fabrics require you to click the edit button to make the fields editable, then click save to save changes. The save on loss of focus behavior is probably undesirable in general, since it's not clear to the user that behavior exists and it could easily lead to inadvertent changes being made live immediately.
