The issue seems to be with Canary, but I wanted to reference it here in case someone else encounters it.

Thanks for your report. When I have time, I will look into that :)

Fixed it on my side by removing the "changed" event after setting the item list.

Fixed in:

• 1.19-1.3.2.1 : 34bce30
• 1.18.1-1.2.2.1 : 8ed9445
