[Bug] Shiny sparkle animation not always showing during Egg Hatch Phase

Describe the bug

When hatching eggs the sparkle animation doesn't always show up.

I investigated a bit and it seems like the animation for each tier only gets loaded if you play with a Pokemon of that tier in your party (and also probably if you encounter a wild shiny for that tier, but I didn't test for that)

Expected behavior

The sparkle animation should always get loaded in so that they always show up when hatching eggs

Screenshots / Videos

Here's what the console looks like when hatching a batch of shiny eggs after opening the game and starting a run with a non shiny Pokemon

After that, I exited to the main menu, pulled more eggs, and started a different run with a tier 2 and tier 3 shiny Pokemon in the team. The tier 2 one was the only one to ever be on the field. When the eggs hatched both tier 2 and tier 3 shinies had their sparkle animation this time, but not the tier 1 shinies
