Last working version: 2.7.1
Vue Version: 3.4.21
Browsers: Chrome 123.0.0.0

Steps to reproduce

• Use a prepend slot in conjunction with the selectable prop on the tree

• Utilize the "selectable" prop to populate the v-model array with selected values

• Trigger a method when a selectable checkbox is selected

Expected Behavior

• Checkbox shows up next to prepend icon

• Selecting the "selectable" checkbox adds the value to the v-model array

• Event click:select is triggered when checkbox is selected

Actual Behavior

Would be awesome if you could help test PR #19795, this is what I fixed so far

The return object prop does not seem to be working, and is returning the object keys

@click:select also does not seem to fire still
i'm also unsure how you got the prepend slot next to the items with children and the down arrow. Checkbox as well

Fixed

Will resolve as a separate fix later

Turns out the prop "activatable" was causing this for me. i didn't need it, so i removed it. I also needed to set
select-strategy="classic". if you want the activatable prop, you should be able to use active-strategy="classic"
