Large animesh objects repeatedly shrink down in a fast loop, almost strobing

1) Set up the avatar skeleton bones in a manner that has a chain considerably stretched out (Usually happens on Wrist -> Pinky3 the most)
2) Create a mesh, rig each vertex to at least some bone in it
3) Export the mesh, upload with rigs and joint positions enabled
4) Set the mesh to Animated Mesh (Animesh). If necessary, wear it, preferably on Pelvis, but it usually happens even on the ground.
4) Confirmed to happen in the latest version of the official Second Life viewer and Firestorm. This DID NOT happen a few years ago.
I can provide files (mesh .dae and animation .anim alongside a script) to recreate the exact scene in the video if desired. The feedback hub does not let me upload these files directly.

I tested this on Firestorm, Firestorm 6.6.8 from 2022, SLViewer, Alchemy Beta and Develop and even the very old Singularity viewer, and all exhibited this issue. So this isn't some new viewer bug and has always existed, especially given Singularity hasn't seen an update in 5+ years.
Not sure how you weren't able to reproduce it on Alchemy, perhaps it was a fluke, but it consistently reproduces for myself.
Here is the bug in all sorts of different viewers-

Upon further testing, I noticed this issue
might
be related to the amount of stretching for each joint, however I cannot confirm either of these possibilities:1) Trying a similar total distance as with the fingers with the tail joints (spreading it across all six) does not seem to cause this issue, unless there is more things at play that I may be missing. However if it is related to the amount of distance between joints, it makes no sense that rotations seem to change how likely this issue is to happen.
2) Another possible cause might have to do with the chain not being directly connected to the mPelvis joint, but I've tried including the bones with a chain down to the mPelvis bone, and it still happens.

Dan Linden Hello Dan Linden, thank you for getting back to me so quickly. I have sent the e-mail as requested.
P.S. I have confirmation that this issue does not seem to happen in Alchemy Viewer, which definitely means it can be an issue that has been introduced recently.
