If the user closes a tab with the "x" button on the tab itself, the tab count is not being updated properly, this is causing the user to see an incorrect number displayed on each new tab they create.
Technical Investigation
This issue is probably caused by the tab closing event not removing the tabs from the tab list, or the issue could be rooted in the new tab functionality itself and we are just using an incorrect number to create new tabs.
