Keep style after pressing enter or return on samp tag

Unlike most inline and phrase elements, after pressing enter on a samp tag I don't get the expected result and the editor doesn't create a <p> tag with a <samp> inside of it but instead it create another <samp> after the first one

Senario:

1/ insert this  html content <p><samp>sample text</samp></p>
2/ put the cursor after the word "text" and press Enter

Expected:

<p><samp>sample text</samp></p>
<p><samp></samp></p>

Actual:

<p><samp>sample text</samp><samp></samp></p>
