What steps will reproduce the problem?
(1) Enter tab switcher, and only keep one card
(2) Create tabs in that card so that it has more than one tab
(3) Click any tabs in the tab group to get back to the tab

What is the expected result?
The animation is smooth.

What happens instead?
The animation jumps a bit.

Note that the animation works fine if there are more than one cards. When there is only one card, it's wider than usual (different scaling factor and height cropping). I suspect the animation issue has something to do with that design.
