Description:

Steps to test this PR:

1. Open this PR on Gitpod or pull down for testing locally (see docs on testing PRs here)
   How can we reproduce this issue?
2. Create a Company and fill out fields like phone, website etc.
3. Create a contact and add the contact to the company
4. Create a non-campaign-based DWC with a variable for a company field, e.g. {contactfield=companyphone} in the content. Add a filter that is fulfilled by the contact form Step 2 eg. Email = not empty
5. Create a landing page and add the DWC to the LP
6. Open the Landing page for the contact from Step 2 and see that no content is rendered.
