 WP_HTML_Tag_Processor doesn't allow to set inline encoded SVG as a source
 for IMG tag. It appeared in WordPress version 6.6

 How to reproduce:

 {{{#!php
 $newSrc = "data:image/svg+xml,%0A%3Csvg width='100' height='100'
 viewBox='0 0 100 100' fill='none'
 xmlns='http://www.w3.org/2000/svg'%3E%3Crect width='100' height='100'
 fill='%23D9D9D9'/%3E%3C/svg%3E%0A";

 $processor = new WP_HTML_Tag_Processor( '<img src="something">' );
 $processor->next_tag('IMG');
 $processor->set_attribute('src', $newSrc);
 $outputHtml = $processor->get_updated_html();

 // $outputHtml contains <img src=""> instead of <img
 src="data:image/svg+xml...">
 }}}
