Natively tabbable items are a[href], area[href], button, input, object,
select, and textarea. HTML5 adds menuitem.  IOW, things people can interact

Consequently, if focus arrives on something the assumption on the part of
the user is likely to be "I can act on this.".   In fact when an element
that is not focusable by default has a tabindex="0" (most elements that
have no mapping), the element is mapped as 'editable text' in MSAA.  As a
consequence, JAWS will read "editable" for the following  <h1
tabindex="0">Some heading</h1>
