What steps will reproduce the problem?
(1) Get enough open tabs in a window so that they shrink to the minimum possible size (with barely enough space for the favicon, or an X to close if it's selected).
(2) Select a different tab by touching it with your finger.

What is the expected result?

Back before the R67 redesign, the tabs would expand to a larger minimum size to give you an easier target to touch (moving more tabs into the big condensed stash on the side to make room for a few larger tabs in the middle).

What happens instead?

Now after the redesign, they don't do that anymore. The UI difference between control-by-mouse and control-by-touch we used to have is gone.

I don't know if this is WAI. If it isn't, it's a regression that should be fixed. If it is, fair enough, but then I have a new usability issue with the new UI: the current tab always has the little X button to close it in place of the favicon, which is fine, but the problem is that this button seems to steal touch gestures from the tab. With any other tab, I can grab it and move it side-to-side to tug on the stash of condensed tabs on either side of the window, or I can long press it and then move it's position in the order of tabs around. I can no longer do that with the current tab, presumably because my swipe or long press action gets eaten by the X button (which doesn't know what to do with it) rather than the tab surface below it. This may have already been an issue before, but it wasn't a big deal in practice because due to the expanded touch targets the tabs were big enough that I could just grab them on a different spot that didn't have the X button over it. But since we removed the tab expansion, the tab is so tiny that the X button takes it up completely and there's no space left I can touch if I want to drag it around.
