I think that all the data associated with such a tab should be copied to the new tab in the target window because: 1. It is "more reasonable" to save all the data when moving tab somewhere (and less surprising for extension developers who use session store) 2. Features such as "Duplicate tab" and "Undo close tab" use session store and therefore are aware of data associated with tabs in session store. I think that "Drag and drop tabs between windows" is the feature of the same category and it should be aware of session store as well. Reproducible: Always
