That is not what the spec says. tabindex="0" is explicitly permitted
as a legal value.

    2. Those elements that do not support the tabindex
attribute or support it and assign it a value of "0" are navigated

character stream.

The spec also states "User agents should ignore leading zeros."
tabindex="0" does not constitute a leading zero. It isn't leading
