EDMC does not emit SquadronStartup event after launching the game

Describe the bug

The first time the player jumps into a game mode after the game has started, EDMC will sometimes fail to emit a SquadronStartup event. Subsequent launches into a game mode (going to menu and coming back) do correctly emit the event.

To Reproduce
Steps to reproduce the behavior:

Prerequisite: CMDR must be in a Squadron.

1. Create a Plugin that makes use of the SquadronStartup event. I have provided an example plugin here
2. Start up EDMC
3. Start up the Game
4. Go into any game mode, e.g. Open
5. The SquadronStartup is not emitted. I have found that to be flaky. Sometimes it does, sometimes it doesn't
6. Go back to main menu
7. Go back into the game
8. This time, the SquadronStartup will be emitted.

Expected behavior

The SquadronStartup event should be passed to the Plugin the first time the user jumps into a game mode

Screenshots
No screenshots, but a Repro video :)

Additional context

This issue does happen outside of Linux/Dirty EDMC Build. People on Windows with a stable build have notified me about incorrect Squadron Handling on my plugin which makes use of this event

No other plugin was loaded in the Repro video.
