Hi Chathurika, We understand your point. But this is not a functional blocker. We will reduce the priority of this issue and as NuwanP mentioned in the ticket, this needs to be fixed from the JS engine level. If we are going to deal with that, it will reduce the performance of the entire data mapper and we cannot go down this path.
@NuwanP: Please report a JIRA against the JS engine and reduce the priority of this issue and keep it opened.
