[sv-ohorvath]

From the logs and video it looks like it either fails to close a tab in one of the steps (results in multiple tabs matching), or fails to swipe right in the second comment

[sv-ohorvath]

Similar problem: #18003 (fails to close the tab)

[sv-ohorvath]

Potential fix landed in 23cc352. Closing the issue. If it fails again we can reopen it.

Same as #20354, #20479 and #20296 which I couldn't reproduce or find an explanation for. Still looking.

[sv-ohorvath]

Last report of this issue was July 26. I think it may have been something fixed in the meantime. I'll close these issues (related ones as well) until it comes up again.

[sv-ohorvath]

Ok, the problem persists, #15624 has the same error.

This issue appears to be related to multiple tests (duplicate tabs title, close button, or tab item):

In this case, the snackbar is displayed, but there is some refreshing of the home screen behind it, so I think that interferes with the visibility of the snack bar.
