<a> is removed on normalize if only child is <img> and it has siblings

[whytspace]

Description

I tried to parse the following html string

<!-- this does not work -->
<p><a href="#1"><img src="https://source.unsplash.com/kFrdX5IeQzI" /></a>Foo</p>
<!-- this works -->
<p><a href="#1"><img src="https://source.unsplash.com/kFrdX5IeQzI" /></a></p>

Parsing worked fine but during normalization the link is removed. The problem seems to be coming from the withRemoveEmptyNodes function

Sandbox

Expectation

The link should not be removed, since it is clearly not empty! It contains an image.
