## Summary of the Pull Request
The TerminalSettings object we create from profiles no longer gets passed into the control, instead, a child of that object gets passed into the control. Any overrides the control makes to the settings then live in the child. So, when we do a settings reload, we simply update the child's parent and the overrides will remain.
