Description
Using for .. of loop in JS when iterating over groups an item may have (DelegateModel.groups) seems to sooner or later trigger a crash. In the meanwhile using for .. in or more old fashioned for loop seems to work fine.
Steps to reproduce the problem:
- Run the attached project
- check the checkbox (=> will use for .. of loop)
- click repeatedly on "toggle selection" => crash
If the checkbox is not checked the example will use different style for loop and no crash will occur.
