Issue Summary

Tables with coloured cell backgrounds lose colours in rendered API output (expand=renderedBody) and JSM Customer Notification emails. The ADF source correctly contains background colour attributes, but they are stripped during conversion to HTML.

Steps to Reproduce

1. Create a comment on a JSM issue with a table containing cells with background colours.
2. Call GET /rest/api/3/issue/{issueIdOrKey}/comment/{commentId}?expand=renderedBody
3. Observe the renderedBody: table is rendered but colours are missing
4. Check the JSM Customer Notification email: table is rendered but colours are missing

Note: The raw ADF body correctly contains the "background" attribute in tableCell.attrs. The colour is lost during ADF → Wiki Markup → HTML conversion.

Email Notification:

Expected Results

Cell background colours should be preserved in rendered HTML in notification email.

Actual Results

Colours are silently stripped: <td class='confluenceTd'> with no colour styling

Workaround

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