<TextareaAutosize/> causing a ton of forced reflows according to the performance tab

[polooner]

Looks like this package adds potential performance issues. All of the purple/red stripes are related to this component.

I can't repro such bad results when profiling this on https://andarist.github.io/react-textarea-autosize/ . Please provide a repro case that could be investigated

I'm seeing the same kind of results in an app I'm working on. I suspect that the reflow takes longer if the page contains many elements that take longer to lay out.

It seems that the calculateNodeHeight function reading scrollHeight is causing the browser to recalculate all the styles and reflow the page. It seems this function is called on every keypress. Is there a way to cache the node height so that it will not be recalculated on every keypress?

Im also running into a similar issue - only happens when theres hundreds of these on the screen at once
