Floating Action Button (top) and Subnavbar Bug

If you have a subnavbar on a page and also a FAB positioned at the top of the page, the FAB will be partially hidden by the subnavbar.
Option to fix this? ( I can add a margin-top, but it seems it is a bug)
Screenshot shows “Kitchen Sink” Subnavbar page with the issue.

What is your page full HTML layout?

Actually, I just added your kitchen sink code for a FAB:

<div class="fab fab-left-top color-yellow"><a href="#" class="">
<i class="icon f7-icons if-not-md">plus</i><i class="icon f7-icons if-not-md">xmark</i></a>
<div class="fab-buttons fab-buttons-bottom">
<a href="">1</a><a href="">2</a><a href="">3</a></div></div>

to your kitchen sink Subnavbar example page.
The layout is just Framework7 Kitchen sink v5.3.0 only
