I have no dog in this fight, Sweaty, but isn't "straightening" just "bending" in the other direction?
Seems to me if you rotate an image and the subject appears to "straighten", then when you rotate the image in the opposite direction it should appear to "bend", no?
Sorry if I missed something important, here.
All these lines and gif's and whatnot are hard on old Howie's brain.

As worded, Howie....you're technically correct.
But your phrase....."it should appear to "bend"
...is missing a key component...to be relevant to Patty's 'finger-bending' issue.
The key component/word is "FALSELY appear to bend".
(In this post...I've highlighted some key words in violet, in response to your question.)
I explained this in detail, in an earlier post....#3621...
.....the 'doll-hand illusion'...in principle.....is completely irrelevant to Patty's apparently moving fingers.
This is due to the fact that the doll hand illusion can only create the illusion/false perception of fingers straightening....not bending.
(The fingers on the doll hand are actually bent, and falsely appear to straighten).
What is needed, for Patty's case, is just the opposite.....an illusion that creates the false perception of fingers...which are actually straight...appearing to bend.
In Patty's case....there are multiple images where her hand is seen edge-on, and her fingers are straight.....so we know that they are straight.
In ONE image....they appear to be bent/curled.....so, the question is....could this curled contour be an illusion/false perception, caused by the twisting of the arm/hand....(the 'doll-hand illusion').
The answer is...it cannot be...since the 'Doll Hand Illusion' cannot cause that false perception....the doll's fingers ARE ACTUALLY BENT...
The ILLUSION is the straight contour....(the doll's hands ARE NOT actually straight).
I used the computer-generated hand, since there's definitely no manipulation of the hand, as it's turned. Spektator's doll hand images can be a little confusing.
To state this a little more simply...
A 'doll-hand illusion' can only cause the illusion of straightening....not an illusion of bending.
This is simple common sense.....do you think you can take a doll, with straight fingers....and, by turning it any which way you like....make them falsely appear to be bent???
I think not.
