Issue Summary

When using the /wiki/rest/api/contentbody/convert/styled_view endpoint https://developer.atlassian.com/cloud/confluence/rest/v1/api-group-content-body/#api-wiki-rest-api-contentbody-convert-to-post, image captions are not included in the rendered HTML.

Steps to Reproduce

1. Use a dynamicContentMacro with a body.
2. In Confluence edit mode, add a image with a caption to the macro’s body.
3. Save the page.
4. The dynamicContentMacro should use window.AP.confluence.getMacroBody to receive the body as storage format and convert it using the mentioned endpoint `/wiki/rest/api/contentbody/convert/styled_view`
5. The macroRenderedOutput.value will contain the image, but not the caption

Expected Results

Render the image with caption.

Actual Results

It doesn't render the caption.

Workaround

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