What steps will reproduce the problem?

(2) Open private window and some website
(3) Close website in private window
(4) Perform repopen closed tab (e.g. even in non-private window)
(5) Closed tab opens

What is the expected result?

The closed tab from the private window should not be available, especially in the non-private window.


What happens instead?

The closed tab, from the private window, opens in the non-private window.

Please provide any additional information below. Attach a screenshot if
possible.

I don't know whether this is considered as a bug, but this should not be reproducible imho.
A private tab should be constrained to the private window. If I reopen a private tab (with the mentioned extension) it should not be possible to available in the non-private window.
I assume this is an issue with the extension, but also with how chromium handles private tabs all together.
