Steps to reproduce:
(repro video day10_149.mp4)
1. open attached project
2. open Script execution order window
3. set priority of Delegevent to the lowest and apply
4. now set Delegevent priority (don't apply yet)
5. enter play mode, window pops up and you apply changes

Actual: SEO does not get applied until entering play mode for the second time
Expected: it should recompile and apply SEO

Reproduced: 5.3.6p3, 5.4.0p4, 5.5.0b3
Did not reproduce: 5.2.5f1 (although, it sometimes recompiled script in runtime and caused on of the calls to fail)
