Bug description

I use swiper with FreeMode to create tooltip dropdown with a scrolling list.

If we wait until the scroll is finished and then close the dropdown then everything will be fine, but if we close the dropdown before the scroll is finished - we get an error "Cannot read properties of undefined (reading 'speed')"

This bug we can reproduced for example with mousewheel scrolling
