This happened to me twice today. For some context, it happened after I booted up my computer and firefox restored the previous session.

These are my logs, if it helps

Can confirm that the same behavior happens to me too. (Sidebery 5.2.0, Firefox 133.0.3)

[cdavie-artium]

I just lost all my group nestings and came to Github to report this issue. (Sidebery 5.2.0, Firefox 134.0b9)

[fb913bf0de288ba84fe98f7a23d35edfdb22381]

Happens to me almost every start, on multiple devices.
