Oops, I assumed the screenshots were taken on meta but I didn’t even think of checking it.
Small but weird behavior. On the regular theme, when we release the mouse button on , it instantly triggers the show or close sidebar’s animation.
On the new theme, when we release the mouse button on when the sidebar is closed, there’s a split second of waiting before the sliding animation is triggered. Doesn’t happen if we click the icon when the sidebar is visible.
I’m probably hallucinating 
Can I leave the group to compare changes with the old theme? I don’t see the leave option.
