HTML code disappeared in <a> tag

Problem/Motivation

Hi,
I have:

• Drupal 10.5.1
• Linkit 7.0.7
• CKEditor5 Open New Tab 1.0.1

When I create a link to a Media with CKEditor (e.g. a PDF file) and open the source, the code is
<a href="/media/558" data-entity-type="media" data-entity-uuid="7d1be872-1028-4890-8909-636a2bd227ed" data-entity-substitution="media">my pdf</a>
but if I add the target="_blank" by the module, the code becomes:
<a href="/media/558" target="_blank">my pdf</a>

What can I do in order to preserve all the html code?

Thanks.
