[Bug]: Collapsible open animation is triggered by splice on underlying data

[ricketyBridges]

Environment

Development/Production OS: macOS Sonoma 14.4
Node version: 18.18.0
Radix Vue version: ^1.5.3
Vue version: ^3.4.15
CSS framework: Vanilla scss

Steps to reproduce

Open a bunch of the collapsibles via the buttons. Then drag and drop to rearrange them.

Describe the bug

Using splice to rearrange an array of collapsibles causes the open animation to fire or flicker.

This occurs on drag start and when a drag ends (but only on the collapsible that is higher up). If all collapsibles start open, it does not occur, user must close/open first.

Expected behavior

If the dragged/spliced collapsible was previously open, it should stay open and not flicker.

Does the solution mentioned here fix it? radix-ui/primitives#1074 (comment)

[ricketyBridges]

Not sure if that solution is applicable here, as I cannot move the class into an inner element without losing animation completely.
