Memory leak risk due to event listeners not removed on componentWillUnmount

Lines 172 to 176 in 0a19cba

    
           componentWillUnmount() { 
        
             if (this.resizeObserver) { 
        
               this.resizeObserver.disconnect() 
        
             } 
        
           }

I'm investigating an interaction glitch with the crop tool, and tangentially noticed that componentWillUnmount assumes it won't occur in the middle of the crop interaction. I imagine this is true in most applications, but it feels safer to ensure the events get torn down. Thoughts?

componentWillUnmount() {
    if (this.resizeObserver) {
        this.resizeObserver.disconnect()
    }
    // Ensure all event listeners are removed
    this.unbindDocMove()
}

Yep makes sense thanks, pushed to master so will go up in next release

	componentWillUnmount() {
	if (this.resizeObserver) {
	this.resizeObserver.disconnect()
	}
	}
