Short description of error
If you add the bake button to the quick favorite menu it will only bake the passes you had selected when you added the button despite the passes you have selected at the moment.
Exact steps for others to reproduce the error
Add the bake button to quick favorite with the "bake type" in Combined.
Now change the "bake type" to Normal.
Go to the viewport and press Q, Bake.
The baking result will be Combined, not Normal as spected.
