I have seen this more for sites where a TON of state is stored in the backend, the site expects the user to have 1 tab that is kept in sync with what the server thinks that user session is doing.

Heck I have seen sites that throw up errors asking me not to open multiple tabs.

I have also seen sites where if I have Tab 1 on Page A, and I open Tab 2 to Page B, then go back to Tab 1 and navigate to Page C, if I go to tab 2 and try to navigate anywhere, it just goes to Page C.

Fun times when the server has too much state.
