"Multiple Select" product attributes do not render HTML tags on the storefront view

[kedarjoyner]

Preconditions

1. Fresh install of Magento version 2.2.3
2. PHP version 7.1.1
3. MySQL version 5.6.35

Steps to reproduce

1. Navigate to Stores > Product under the Attributes header.

2. Set Catalog Input Type for Store Owner to Multiple Select. Make sure product attribute values include html tags. You must add at least two attribute values. Example below:

3. Navigate to Storefront Properties. The following two properties must be set to Yes.

4. Navigate to Stores > Attribute Set under the Attributes header.

5. Select "Default"

6. Add your newly created Product Attribute under Product Details. You can see my attribute of support under this group below:

7. Navigate to Catalog > Products and create a new product

8. Select both of your product attributes:

9. Navigate to the product page within your browser. Your product attributes will be viewable under the More Information tab:

Expected result

1. The expected output would be rendered html tags. If a product attribute value is wrapped in an tag, the editor would expect to see that element as a link.
2. The editor expects to see this because they have selected Yes under the Allow HTML tags in the storefront within the created Product Attribute (see above screenshot for reference)

Actual result

1. Html tags are rendered as plain text
