Minor issue in Figma Slides:

If you set all the slides to animate (e.g. dissolve), then this layout:
[ 1 ] [ 2 ] [ 3 ] [ 4 ] [ 5 ]
works as expected. Changing slides dissolves the view between all of them.

But, if you hide a slide (using “Skip slide” option):
[ 1 ] [ 2 ] [ 3 ] [ 4 ] [ 5 ]
then the animation works between 1-2 and 4-5, but there’s no animation between 2-4. The skipped slide causes the transition to be instant - no dissolve, no push, nothing.
