2023463 - Cycling through tabs in recently used order does not scroll the tab strip to the selected tab in some cases

Status: NEW

(Firefox :: Tabbed Browser: Tab Groups, defect)

Description

[Denys [:denyshon]]

Preconditions:

• Enable Vertical Tabs.
• Enable "Ctrl+Tab cycles through tabs in recently used order".

Steps to reproduce:

1. Open several tabs in a tab group.
2. Collapse the tab group.
3. Switch to a tab that's not in that tab group.
4. Make sure that the tab group is not visible on the tab strip (i.e., there are enough tabs between the current tab and the tab group).
5. Use Ctrl+Tab to switch to one of the tabs inside the group, but not to the previous one (it should be at least the third in the carousel).

Expected results:
The tab strip autoscrolls to the collapsed tab group with the selected tab highlighted.

Actual results:
The tab strip doesn't autoscroll, even though the selected tab is highlighted inside the tab group.

Note:
This is reproducible in both Nightly and Release. I'm on Windows, and I haven't checked other platforms.

Since nightly and release are affected, beta will likely be affected too.

The Bugbug bot thinks this bug should belong to the 'Firefox::Tabbed Browser' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.
