Unsubscribing from "SceneView.duringSceneGui" in OnDisable() is ignored when unsubscribing more than once at the same time
Reproduction steps:
1. Open project “TestProject”
2. Open scene “TestScene”
3. Make sure 2 Inspector windows are open
4. Select the “TestBehaviour” GameObject
5. Hover the mouse over the Scene view and observe the log message “On Scene GUI 1“ being spammed in the console
6. Deselect the “TestBehaviour” GameObject
7. Hover the mouse over the Scene view
Expected result: the log messages are no longer spammed in the console
Actual result: the log messages “On Scene GUI 0” is being spammed in the console
Reproducible with: 2020.3.44f1, 2021.3.17f1, 2022.2.4f1, 2023.1.0b2
Reproducible on: macOS Catalina 10.15.7 (Intel)
Note: a single Inspector window opened gives expected results - unsubscribing from “SceneView.duringSceneGui” is done once

Resolution Note:
The example code is incorrect. The line responsible for removing the "static" delegate is actually referencing an instance method. Changing the "StaticOnSceneGUI" method to "static" elicits the expected behaviour.
