Current behaviour:
The session list unfolds completely when the following happens:

• When the focus shifts to UnityEditor. In other words, when it is in the foreground.
• When played in Editor
• Immediately after Capture with MemoryProfiler
• When Snapshot data is selected in Memory Profiler

Expected behaviour:

1) General behaviour upon opening of the memory profiler or opening of a snapshot (no capture taken):

• At any given time, the session list should retain information about which sessions are open and which sessions are closed according to how the user has set up their workspace
• If it is not possible to retain information when the memory profiler is closed or unfocussed, the expectation is at the next opening/focussing, the latest session should be open and the other sessions closed. 

2) Behaviour when capturing a snapshot

• When capturing a snapshot, the corresponding session should be opened. All the other sessions should retain the current state (if open, stay open. If closed, stay closed).

3) Behaviour when opening an existing snapshot

• When opening an existing snapshot, all sessions should retain the current state (if open, stay open, if closed, stay closed)

• When a new capture is taken, the corresponding session should be opened to allow users to immediately inspect the capture.
