If you have multiple tabs open in the same browser, they are all in the same session and share the same session properties. Is there any information available in Perspective regarding identifying the different tabs?
For context, we are trying to implement history navigation, and want the page histories to be separate across tabs.
As you said, the tabs will share the same Perspective session ID because the browser is running the same session. This might work for your use case: You could reference the pageID of your page (page > props > pageID) because the pageIDs will not be shared across tabs but they won’t be repeated if the tab is closed.
