Breaks <TransitionGroup>s absolutely everywhere whenever mounted

[YCMitch]

After a hair-pulling amount of trial-and-error, I've deduced that whenever this component is mounted, all transitions from <TransitionGroup>, <CSSTransitionGroup> and <SwitchCSSTransitionGroup> immediately stop working.

I have absolutely no idea why. I'm guessing this an issue report this vague it'll never be fixed, so does anyone know of an alternative to this component?

Same here, after investigation of issue with react-select package i've found that root cause is autosize input. react-transition-group stops working on page which mounts Select -> AutosizeInput
