See if there's a way to not use global state to open the context menu

[JackWilb]

It doesn't seem like this component should depend on values stored in global state. It seems a lot like this component ought to manage its own position values, and use a v-model pointing to a boolean stored in the component where the menu will appear. I found a nice article explaining how v-model works, and how it can be used in custom components: https://dev.to/vue-storefront/vue-during-coffee-break-using-v-model-with-custom-components-3bo9.
