WP accessibility – .fontsize – special headings

Hi,

with the plugin WP accessibility you can enlarge font sizes by switching.

All works fine with normal h1, h2, …. But I can’t manage to get it work for special headings:

.fontsize, .fontsize h1, .fontsize h2, .fontsize h3, .fontsize h4, .fontsize h5, .fontsize h6, .fontsize p, .fontsize li:not(.a11y-toolbar-list-item), .fontsize label, .fontsize input, .fontsize select, .fontsize textarea, .fontsize legend, .fontsize code, .fontsize pre, .fontsize dd, .fontsize dt, .fontsize blockquote, .fontsize  #top .av-special-heading-tag {
    font-size: 140% !important;
    line-height: 1.4;
}

.fontsize #top .av-special-heading-tag
is a wrong selector.
I tried also
.fontsize h2.av-special-heading-tag

On the page-link below I have both – a normal h2 and special heading h2
