Sub-tasks must inherit security level from their parent when moving issues between projects

[amal Abdallah]

When moving an issue with its sub-tasks from a project to another and even i set the security level for the parent, the moved sub-tasks don't inherit security level from them.

So, their security level is empty.

As workaround, i change the security level for parent to "None" then i affect it to the mentioned security, after that the Sub-tasks will be automatically inherit it.

I want that all moved sub-tasks inherit security level from their parent when moving issues between projects.
