Multi-edit Ad campaigns: tags not saving after edit tags

[ifarzana]

When editing tags for multiple selected Ad type campaign items and clicking save, the changes do not persist as expected. Instead, an error message appears prompting the user to select a display ID.

Steps to reproduce

• Navigate to the Campaigns page.
• Select multiple Ad type campaigns.
• Click on With selected drop-down and choose Edit tags.
• Enter a new tag name.
• Click Save twice.

Expected behaviour
The updated tags should be correctly saved and reflected on all selected campaign items.

Actual behaviour
Tags are not saved as expected.
After clicking Save twice, an error appears stating:
Please select one or more displays.

Additional notes
The issue seems to occur specifically when attempting to edit tags for the type Ad. Editing tags for List type campaigns do not seem to trigger this issue.

This seems to be a validation happening in lib/Controller/Tag.php -> editMultiple for the Ad Campaigns that prevents adding the tags.
