We should rename that variable (it's not just about icon) but we should do that separately.

One thing I note here is that in the documentation of react-resize-aware, it mentions how width would be null the first time the component is rendered:

This object contains the width and height properties, these properties are going to be null before the component rendered, and will return a number after the component rendered.

https://www.npmjs.com/package/react-resize-aware#api

The "fun" thing about null is that, in the context of these sorts of comparisons, it's treated the same as zero (related, specification).

So:

let width = null;
console.log( width < 160 );
// true

So we'll always apply the is-small class on the first render, even if it ends up being that the element will actually occupy a large width.

I guess my question is:

  • Must we have at least one of is-large, is-medium, or is-small, and therefore it would be okay to use is-small as the default until an accurate value can be determined?
  • Otherwise, would it be more correct to wait to assign any of these modifier classes until the true width can be determined?

For context, I think this may be contributing to some intermittent failures in the end-to-end tests, where we're trying to click "Try again" when an embed fails, but the placement of the button might be shifting around because it is rendered after the "instructions" which are hidden while is-small class is applied.
