api.Window.sessionStorage - Safari doesnt support sessionStorage on Duplicate tab
What type of issue is this?
Missing compatibility data
What information was incorrect, unhelpful, or incomplete?
The page says that Safari has full support for sessionStorage. But sessionStorage defines that on tab duplicate the sessionStorage must be maintained. This is not the case in Safari.
What browsers does this problem apply to, if applicable?
Safari
What did you expect to see?
When using sessionStorage on a safari browser tab, and duplicating that tab the sessionStorage should be maintained
Did you test this? If so, how?
I tested it by adding things in sessionStorage and then duplicate in safari, chrome and firefox and the behaviour of safari doesn't follow the indication of the documentation
Can you link to any release notes, bugs, pull requests, or MDN pages related to this?

Duplicating a tab copies the tab's sessionStorage into the new tab.
Do you have anything more you want to share?

see https://github.com/mdn/content/issues/30598#issuecomment-1832088200, this is not a bug, this is just the default behavior - sessionStorage does not shared between different tabs but on same-origin iframes
