Text based swatches returning incorrect results in layered navigation

[JamesAllwood]

When using a text based swatch in the layered navigation, if a store contains values that all start with the same value followed by a space, selecting one of them, selects all of them, and the parameter in the URL only contains the first section.

For example, if I'm listing shoes, and have the values 13 and 13 Child available in my text swatch, clicking on the 13 Child in the layered navigation, also selects 13, and the results are incorrect.

Based on tests, this seems to be limited to text swatches only

Preconditions

Magento Version : 2.3.1

ElasticSuite Version : 2.76

Environment : Production mode

Third party modules : None

Steps to reproduce

1. Create new text based attribute, and populate with the values 13 and 13 Child. Set the attribute to be available in the layered navigation
2. Assign attribute to attribute set
3. Create a new product and assign value 13
4. Create a second new product and assign value 13 Child (ensure both products are assigned to the same category
5. Visit the category on the frontend and filter for the value 13 Child

Expected result

1. I see just the product that has been assigned the 13 Child attribute value

Actual result

1. Both the 13 and 13 Child attributes are selected
2. The parameter in the URL reflects only the value 13 rather than 13+Child
3. The results show only the product that has the 13 value assigned to it, and not the 13 Child value

Before filter is applied:

After filter for 13 Child is applied:

Confirmed.

We'll try to address this one on next 2.7 minor.
