transition slide will become not smooth with min-height and min-width.
https://svelte.dev/repl/90fdf9a3faa645aaa1e18201cf29e9cf?version=4.0.3

transition slide not smooth when with min height or min width.

I think we can set min-height or min-width to be 0 to keep slide smooth when run animation.

I didn't add a test case because I don't know how to test this case.

I'd be happy to add test cases, if any suggestions can be given.
