Hello,
We try to implement the scheduler split feature in our scheduler. At the moment we get an error when we try to split a scheduler.

vue.runtime.esm.js:1897 TypeError: this.selectedCollection.includes is not a function

Reproduced with react-tooltips demo

Reproducible on Grid demo by changing appendTo to adopt.

The error is being caused because of the use of adopt in our Core, which will need deeper investigation to fix it.
