It is possible to make the Standalone Profiler NOT record in Editor mode even when Editor recording is selected.
This is reproducible in an empty project:
In Editor Mode open the Standalone Profiler [Window->Analysis->Profiler (Standalone Process)]
Notice that it displays [RECORDING PLAY] and has Playmode selected and it is NOT recording (as expected)
Switch from Playmode to Editor
Now it displays [RECORDING EDIT] and starts recording (as expected)
Close the profiler
Close Unity
Start the Unity Editor again
Open the Standalone Profiler again
Notice that it displays [RECORDING PLAY] and has Playmode selected and it is NOT recording (as expected)
Switch from Playmode to Editor
Now it displays [RECORDING EDIT]
Also notice that it is not recording this time
