Whenever I go through a slideshow of pictures in a community in tile view, such as !photography@piefed.social, the behaviour is a bit janky for me.
On Firefox in android, swiping right moves one picture at the time, but sliding left (and forwards in the slideshow) sends me through a bunch of pictures making it difficult to navigate.
On Firefox in desktop (Linux) and moving to the right using arrow keys, the picture display slowly drifts to the left: After going through 20 pictures, half the image on display is outside of my screen. With every new picture it moves further to the left.
In both cases the X button moves along.
Oh no. I bet that was me in 8d801dc683. I'll try to repair it.
