Issue Summary

On the "Version History", the changes made in the page are not announced by the screen reader.

Steps to Reproduce

1. Open Confluence Cloud homepage.
2. Open a page that has at least two versions containing text additions, deletions, and formatting changes. 
3. Navigate and activate the "More options" button > Select "Version history" link.
4. Using a screen reader, navigate to the page content which has changes.
5. Observe that the comparison difference for the changes made are not announced by the screen reader.

Screen Recording

Actual Results

Green color highlight and underline for added line, red highlight and strikethrough for deleted line are used to identify the comparison difference in the main page content visually; however, these changes or updates shown on the page are not announced by the screen reader.

This will make it difficult for screen reader users to distinguish changes or updates made within the text of the page.

Expected Results

All content changes must be programmatically determinable by assistive technologies. Screen reader users should receive clear context about what was modified without relying on visual formatting or color.

In this scenario, we can apply following changes -

• Deleted text should be conveyed as deleted using semantic <del> element, or visually-hidden text like <span class="sr-only"> Deleted: </span>.
• Added text should be conveyed as inserted/added using semantic <ins> element, or visually-hidden text like <span class="sr-only"> Added: </span>.

Workaround

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