Hi,

in a Treeview bound to flat data (probably does not matter), if I have 3 items, and I drop the first 2 in the last, the loading indicator is stuck.

Stackblitz repro: https://stackblitz.com/edit/angular-xiwrcwsx?file=src%2Fapp%2Fapp.component.ts

Can you please take a look at it?

Best regards,
Michael
