fix issue for vue 3.2.x

[davidmeirlevy]

Suggested merge commit message (convention)

Type: Message. Closes #000.

---

Additional information

from vue 3.2.x - every property on the data becomes reactive() and not ref(), and since that version - every getter from the reactive proxy returns a reactive proxy of the internal property.
because of that, using methods under the instance is throwing errors because the "this" context is the proxy and not the instance.

For example – encountered issues, assumptions you had to make, other affected tickets, etc.
