Steps to reproduce

What is expected?

When trigger leave, the font color should translate from red to default.

What is actually happening?

1. Properties in class *-leave-from not work.
2. The class *-leave-from affects the normal operation of transition component.

The reason is related to the process of adding/removing css-class, i would like to fix it.

It looks like adding a property to be removed right away (in this case the color: red being only in leave-from) breaks the transition. To workaround it, you can add a color property to .test-leave-to

An alternative workaround is to put transition: none; in .test-leave-from.

Thanks in the first place.

In fact, i create this example on purpose. Because i find current logic does not deal with this scence when im dealing with another issue.
