What happened?

Actual Result

Overview

There is no indication in the tab list that a tab is part of a Split View. The lack of this creates accessibility issues in the following scenarios.

Scenarios

Scenario 1

• Given that a user has created one or more Split Views,
• When the user has switched to a tab that is not a member of a Split View,
• Then it becomes unclear in the tab list which tabs are members of a Split View.

Scenario 2

• Given that the user has duplicate tabs open,
• When at least one of the duplicate tabs gains membership into a Split View,
• Then it becomes unclear in the tab list which of the duplicate tabs is a member of said Split View.

Scenario 3

• Given that the user is visiting the same domain across at least 2 tabs,
  • And the Sidebar Width has been toggled to narrow,
• When at least one of the tabs visiting the same domain gains membership into a Split View,
• Then it becomes unclear in the tab list which one of the tabs visiting the same domain is a member of said Split View.

Expected Result

There should be a clear affordance provided in the tab list that indicates tab membership in a Split View.

References and Recommendations

Arc handles this by visually merging tabs that are members of the same split-view in the tab list, but there might be less heavy-handed options (e.g., reordering relevant tabs so that they're adjacent to one another in the tab list and using a UI element to make it clear that they're currently part of a single split-view).

Reproducible?

• I have checked that this issue cannot be reproduced on Mozilla Firefox.

Bump this! This one is essential if the browser is using split view.
