What the heck is this behavior?

My dog is a miniature pincher/mini poodle mix, plus some other stuff (rescue). For her entire life, at almost every meal she tries to flip her bowl of kibble over, spilling it everywhere or covering it. Then she’ll take one piece and run to another room with it to taste it. Only then will she come back to eat the spilled food.

I’ve seen other posts here that mention burying, but she’ll still eat the food right away, and she has done this almost every meal for 8 years lol. Also the running to another room with one piece feels like an added wrinkle.

Any idea what’s going on there?? Thank you!
