And don't allow new request being associated with existing pending request if the requests are from different origin. This patch also set proper principal to nsItransferable for clipboard write in various cases, - Copy image via context menu. - Copy current selection via keyboard shortcut or context menu. - Data is provided by script when copy operation is triggered via keyboard shortcut or context menu. - Clipboard data is put via async clipboard. Depends on D190761 Differential Revision: https://phabricator.services.mozilla.com/D190796
