Using “Freeze To World” with “VRC Parent Constraint” causes the offsets to become incorrect.

When "Rebake Offsets When Unfrozen" is turned on in the "VRC Parent Constraint," and "Freeze To World" is activated from the animation system to freeze the object in the world, the offsets become incorrect.
I created a simple gimmick similar to the one shown in the Developer Update video ( https://ask.vrchat.com/t/developer-update-30-may-2024/24821 "VRChat Constraints Revisited") and tested it. The video is attached.
The first half of the video shows the scene with "Freeze To World" being used while "Rebake Offsets When Unfrozen" is turned off. The second half of the video shows "Freeze To World" being used with "Rebake Offsets When Unfrozen" turned on.
In the second half of the video, the cube moves instantly when "Freeze To World" is activated. The offsets are not rebaked to maintain the positional relationship between the hand and the cube, which leads me to believe there might be a bug in the "Rebake Offsets When Unfrozen" option.

”VRC Parent Constraint”の”Rebake Offsets When Unfrozen”をオンにした状態で、アニメーションから”Freeze To World”を操作してオブジェクトをワールド固定するとオフセットが狂います。
以下のDeveloper Updateで紹介されている動画（ https://ask.vrchat.com/t/developer-update-30-may-2024/24821 ”VRChat Constraints Revisited”で紹介されている動画）と同じようなシンプルなギミックを作って検証してみました。その動画を添付します。
動画の前半は”Rebake Offsets When Unfrozen”をオフにして”Freeze To World”を操作するシーンです。
後半は”Rebake Offsets When Unfrozen”をオンにして”Freeze To World”を操作するシーンです。
動画後半では”Freeze To World”を操作するとキューブが瞬間的に移動しています。
手とキューブの位置関係を維持するようなオフセットのリベイクは行われず、おかしな挙動をしていることから”Rebake Offsets When Unfrozen”のオプションにバグがあるのではと推察いたします。

Constraints "Freeze To World" comes back to the first target before freezing
Kainet
Ok so, in my avatar, I use glasses that I can move around in different positions and drop in to the world, for some reason now whenever I enable "Freeze To World" on the constraint, It comes back to the first target and then It freezes instead of getting freeze in place. This setup used to work before this patch, and I've tried updating the avatar but It still happening, I guess I need to change the way I do the animation in the mean time. . .
