Issue Summary

SLA condition "Comment: By Customer" does not re-start SLA when assignee is added as request participant.

Steps to Reproduce

SLA configuration:
Start counting time when: Comment: By Customer
Finish counting time when: Comment: For Customers

In the above configuration, customer's comment triggers start SLA
Then, assignee reply to the customer which stop the SLA.
After that,add asignee in request participant then the reporter add a comment.
SLA does not re-start calculation

Expected Results

SLA should be restarted even when the customer added comment with asignee in request participant.

Actual Results

Workaround

We recommend that the agent or assignee is not added as a request participant on the same work item, and is not part of the same organization as the customers.
Remove the assignee from request participant will re-start the SLA.
