Cocos Creator 3.4.0. Default cocos sprite frames don't go to the auto-atlas and break batching

Hi all. I pack all my images into auto-atlas to have small amount of draw calls. It is great feature, thank you all! But I noticed the default sprites provided from cocos aren’t go to this atlas.

Here in the screenshot, you can see default sprite splash interrupts batching because it is outside of atlas.

I can duplicate this asset to my images folder and use it instead of provided default folder of cocos, but I think maybe it should be packed with other images by default?

I can ask engineering to have a look.

Default sprite splash is internal asset，so it unsuited to packed with other images by default.
