Change the default tags for HTML5 support

I need to use the strikethrough button so I added this feature through the toolbar method. The problem is the selected text is surrounded with strike instead of s or del tag. As you know the strike tag is not supported in HTML5.

How can I change the default tags?

Expected behavior: <s>Text</s> or <del>Text</del>

Actual behavior: <strike>Text</strike> Link
