react-image-gallery: Uncaught TypeError on unmounting

Since v0.8.8, when an image gallery is unmounted, an Uncaught TypeError occurs:

Uncaught TypeError: Failed to execute 'observe' on 'ResizeObserver': parameter 1 is not of type 'Element'.
    at image-gallery.js:137
    at invokeFunc (index.js:160)
    at trailingEdge (index.js:207)
    at timerExpired (index.js:195)

I believe it is introduced by adding the debounce in b273f9d0da94.
