> Dragging an image that is directly included like `<img src="some image"/>`
> works fine, without exception. However, there are (at least) two other cases
> when the IAE is thrown:
>
> - Dragging an image that is part of an hyperlink, like `<a href="some
> url"><img src="some image"/></a>`.
> - Dragging an image encoded as base64.
>
> The IAE happens only on macOS, where a native image is created in
> `GlassPasteboard.m` from an URL, and in those two cases the generated image
> has 0x0 dimensions:
>
> `<NSImage 0x... Size={0, 0} ...>`
>
> which leads to `ByteArrayFromPixels` being called with a null byte array.
>
> The included test reproduces the case by directly pushing the `MacPasteboard`
> content (instead of adding a more complex test with a webView and a drag and
> drop gesture).
