Self-closing tags removed when exported

When looking at bootstrap studios HTML editor I see that the link has self-closing tags:

<link rel="stylesheet" href="header.css" />

however when I run the export to a local directory I get:

<link rel="stylesheet" href="assets/css/header.css">

(notice the closing / is removed when exported).

Is this expected, or should the export command be removing the / ?

Bootstrap studio: 2.7.0

It's not required for HTML.

You are building an HTML5 site, not a XHTML site with the app.

HTML5 DocType - <!DOCTYPE html>, closing tags not required.

XHTML DocType - <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">, closing tags ARE required.

XHTML is stricter than HTML(5) -

However, I do understand your thought that if it's in the app like that you'd expect the export to also to be like that.
