[DEFECT] showFields Field Variable for relationship fields incorrectly displays image when no tags are present

Problem Statement

When using the showFields Field Variable for relationship fields in a content type, the output unexpectedly includes an image when the related content entry has no tags. This appears to be a fallback or rendering issue, the field is showing an image instead of leaving the area blank or showing no data.

This leads to misleading visual output and inconsistent rendering when relationship entries are missing tags.

Steps to Reproduce

1. Go to a Content Type that has a relationship field and a tags field
2. Add the showFields Field variable and set the value to "image, title, tags" or "title, tags"
3. Create or edit a content entry of that content type
4. In the relationship field, there should be entries that have no tags

Acceptance Criteria

• When no tags are defined, the relationship field should not display any image or placeholder, it should just be empty

Severity

Low - Minor issue or cosmetic

Start by reproducing the issue with a relationship field whose related entry has no tags, using showFields set to "image, title, tags" or "title, tags". Trace the rendering entry point for relationship fields and the tags fallback, then verify that an entry without tags produces no image or placeholder.
