Description

After migrating from Jira Data Center to Jira Cloud, for rich text embedded images with a percentage based width, the images have excessive whitespace/padding around them.

Related tickets:

• If images are showing with size 200x183 rather than original size, please see: https://jira.atlassian.com/browse/JRACLOUD-98374
• If images that are inline (side by side) are showing vertically in Cloud, please see: https://jira.atlassian.com/browse/JRACLOUD-98849

Steps to Reproduce

1. On a Jira Data Center instance, create issues with embedded images using the following wiki markup pattern:

   •  !image.png|width=50%!

      — percentage-based width

2. Migrate the project to Jira Cloud using the Jira Cloud Migration Assistant (JCMA).
3. View the migrated issues in Jira Cloud.

Alternative reproduction steps (without migration)

1. Issue can be reproduced via this reproduction link

2. Alternatively - In editor examples (https://atlaskit.atlassian.com/example?groupId=editor&packageId=editor-core&exampleId=kitchen-sink&mode=none) reproduce content with the following ADF where image.jpg is set to a wide landscape aspect ratio image, eg https://placehold.co/800x300

{
  "type": "doc",
  "version": 1,
  "content": [
    {
      "type": "mediaSingle",
      "attrs": {
        "width": 50,
        "layout": "center"
      },
      "content": [
        {
          "type": "media",
          "attrs": {
            "type": "file",
            "id": "image.png",
            "collection": ""
          }
        }
      ]
    }
  ]
}

3. Observe large whitespace above and below the image in both editor and renderer:

Expected Result

Images should render with the same dimensions, proportions, and layout (including inline positioning) as they had in Jira Data Center.

Actual Result

The percentage width is preserved, but the height is incorrectly assumed by the renderer, producing large vertical padding — especially visible on wide/landscape images.

Impact

Embedded images (step-by-step instructions, test evidence, diagrams) are difficult to read after migration. 

Workaround

Open the affected issue in Jira Cloud → Edit → click each image → drag the resize handle to restore the desired size. This must be done per image, per issue.
