Is this normal ragdool behavior? Please advice. Breeder says these traits are normal and I am not convinced.

I got a 3 month old female kitten from one of the most reputed breeders in NY. Over a 40 day period, the unexpected behaviors I have observed:

• she fixates on 1 denied boundary (a recliner where I work at times) and I have lifted and shifted her gently like 5000 times over 40 days but she won't give up
• when I am on this recliner and she's denied lap, she would walk toward me in prey mode hiding behind all the furniture, this intense stare in her non-blinking eyes, and after observing quietly she would pounce directly on my chest. Not once, obsessively for 40 days she repeated this behavior. Despite million very gentle denials and lifts and shifts
• when denied something repeatedly, she would go into rage zoomies (not playful certainly rage based on body signs) for 2 to 3 hrs at times. She would run all over thr house, scratch everything which she was asked not to, if I tried to lift and shift she would impulsively try to bite my hand. She would aggressively maul the mouse toy at times right next to my feet. You could see this wasn't playful but strong tantrum energy.
• when I would ignore her for intense meowing, she would run and block my path and meow more. She would aggressively block my path after I ignored her rage zoomies.
• at times while going through rage zoomies, she would rush past my legs and push my leg really hard as if to warn me. I would change room she would run behind me to the new room to repeat
• one day she was misbehaving so I ignored her when she cried for my lap as I sat on the table. She jumped on my neck from behind

Any time I shared these details with the breeder, she went like this is normal kitten behavior and energy.

Would appreciate any feedback or color here. Thank you.
