The text domain defined in load_child_theme_textdomain() should be used to translate all strings in the child theme. In the event that a template file from the parent has been included, the textdomain should be changed from the one defined in the parent to the one defined by the child.
I am defining a different text domain for child-theme but plugin is still using parent theme's textdomain. You can check example child-theme from http://theme.firmasite.com/child-theme/ if you want. When rescanning, plugin generates language with parent's textdomain.
Is there a workaround for it?
