If anyone has something similar, this might or might not be related to an issue we had (v. 8.3.2)
If you have no windows with isModal set to true, and you have some with it set to false, you get this error
If there is at least one window with isModal = true, or other windows do not have isModal set (or set to an undefined variable), it works OK
Is this still the case?
It’s not working for me, it does work for any value other than an empty string, seems to be interpreting it as null and therefore the getter, not the setter.
Admittedly, I am using the react version
