📝 Provide detailed reproduction steps (if any)

I am adding a content in CKeditor 5 .The html content is

<div style="text-align:center;">
<button class=" btn btn-primary d-inline-block mt-4" data-bs-dismiss="modal" href="javascript:void(0);" id="closebtn"><span class="link">Close</span></button></span></div>

✔️ Expected result

<div style="text-align:center;">
<button class=" btn btn-primary d-inline-block mt-4" data-bs-dismiss="modal" href="javascript:void(0);" id="closebtn"><span class="link">Close</span></button></span></div>

What is the expected result of the above steps?

❌ Actual result

<div style="text-align:center;">
<span class="html-object-embed ck-widget ck-widget_selected" data-html-object-embed-label="HTML object" contenteditable="false"><button class="html-object-embed__content btn btn-primary d-inline-block mt-4" data-bs-dismiss="modal" data-ck-unsafe-attribute-href="javascript:void(0);" id="closebtn"><span class="link">Close</span></button></span></div>

What is the actual result of the above steps?

❓ Possible solution

I see there is a toObjectWidgetConverter() function in converter.js under html-support package which is converting to this.
Is there a way to stop this conversion.
