Issue Summary

If a customer sends an email to Jira Service Desk which is in HTML format and contains over 590 rows this is not converted to ADF and rendered in the new issue view. This applies both to the description field when the issue is first created and comments from email.

This is also the same for comments over 590 rows that contain formatting in the old issue view format.

Steps to Reproduce

1. Create a JSD project with an incoming email channel.
2. Create a ticket.
3. Send email response to the ticket with lots of formatted content that is over 590 rows.

Expected Results

The comment is visible in the old and new issue view.

Actual Results

The comment is only visible in the old issue view and fails to be converted to ADF for the new issue view.
The below GraphQL query shows both old and new issue view comment bodies and you will see the new issue view bodyAdf is null

{
  issueComments(issueIdOrKey:"<ISSUE-KEY>")
  {
    nodes{
      bodyAdf
    }
    nodes{
      renderedBody
    }
  }
}

Workaround

Edit the comment or description in the old issue view to reduce the length to be below 590 rows.
