/**
 * BrowserInstanceService is responsible for generating and storing a unique ID for the tab.
 * THe ID is stored in the session storage, so stays the same even after page reload
 * as long as the tab stays on the same domain.
 * This ID will be the same for all frames/context in the tab as long as they are on the same domain.
 * Currently, this is simplified version which has this limitation:
 *  - It does not cover the case when tab is duplicated -
 *      browsers copy storage when duplicating tabs so the ID will be the same
 *    To cover this case we need to implement a communication between tabs which requires asynchronous initialization.
 *    This is not implemented yet as requires bigger refactoring.
