Lazy image loading breaks notification mails for an added screenshot

Steps to reproduce

HTML in notification mail for image before 9.5:

<p dir="auto">
<a class="no-attachment-icon" href="URL_OF_IMAGE" target="_blank" rel="noopener noreferrer">
<img src="URL_OF_IMAGE" alt="ALT_FOR_IMAGE" style="max-width: 100%; height: auto;">
</a>
</p>

HTML in notification mail for image in 9.5.x:

<p dir="auto">
<a class="no-attachment-icon" href="URL_OF_IMAGE" target="_blank" rel="noopener noreferrer">
<img src="data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==" alt="ALT_OF_IMAGE" class="lazy" data-src="URL_OF_IMAGE" style="max-width: 100%; height: auto;">
</a>
</p>

What is the current bug behavior?

Lazy loading images from within mail client does not work.
