Issue Summary

When a user previews an image on a page in view mode, the image flickers if the card macro is being used under the excerpt macro. 

This is reproducible: only under the customer environment

Steps to Reproduce

1. Create a page in Confluence cloud.
2. Add an excerpt macro to the page. 
3. Further add the card macro 
4. Add the image to the card 
5. Add more than five images under the excerpt macro
6. Now use the same excerpt on another page by using the insert excerpt feature. 
7. The page with the insert excerpt starts flickering continuously.

Expected Results

The image should remain stable and not flicker during full preview mode.

Actual Results

The image previewed in both view and edit mode flickers

Workaround

Currently, there is no known workaround for this behaviour. A workaround will be added here when available
