Seeing unexpected/possibly faulty HTML class tags in the output

Expected behavior

1. No class tags when there are no classes for a certain HTML element
2. No class names starting with a -.

Actual behavior

The diffs are compared to phpDocumenter 3.4.3

1. No class tags when there are no classes for a certain HTML element

-    <a href="classes/WpOrg-Requests-Auth.html#method_register">register()</a>
+    <a class="" href="classes/WpOrg-Requests-Auth.html#method_register">register()</a>

The class="" is redundant.

2. No class names starting with a -.

-                    <section class="phpdocumentor-sidebar__category">
+                    <section class="phpdocumentor-sidebar__category -namespaces">

I'd expect the class name either to be phpdocumentor-sidebar__category-namespaces - i.e. without the space before the - - or this to be two class names and the second class name to not start with a -.

While the above may be intentional, to a casual onlooker, like me, it looks like an error.
