Describe the bug:

I added the [Ecommerce] Average Sales per Region visualization, and I'm getting this error when I click on a country in the map. It looks like it's trying to add a filter but can't. Not sure if it's related to this PR or if I should file a separate issue. Confirmed this is an issue in master and filed an issue #

Steps to reproduce:

1. Install the ecommerce
2. Navigate to Canvas
3. Create a new workpad
4. Click on Embed Object
5. Add the [Ecommerce] Average Sales per Region visualization
6. Click on a country
7. Observe the error.

Expected behavior:
Either a filter should be applied, or the regions should not be interactable

Screenshots (if relevant):

Errors in browser console (if relevant):

Any additional context:
This is a map visualization saved object and not a map saved object.

Embedded visualizations try to directly manipulate the filter bar when filter interactions occur.

#43411 is going to make those filters bubble up through embeddable actions instead so that anyone can handle those filter interactions as they choose.
