'0' can be both a number and a length. But here,
in this sub-test, the width CSS property requires
a length type and not a number type. So, the
attr() function generates an invalid declaration.

bottom: 100px;
width: 0px;
width: attr(attr-test-invalid2 length, 100);

/*
'100' is not a valid length value.
So, the attr() function generates an invalid
declaration.
