make an html svg object also a clickable link

Actually, the best way to solve this is... on the <object> tag, use:

pointer-events: none;

Note: Users which have the Ad Blocker plugin installed get a tab-like [Block] at the upper right corner upon hovering (the same as a flash banner gets). By settings this css, that'll go away as well.

I had the same issue and managed to solve this by:

Wrapping the object with an element set to block or inline-block

<a>
    <span>
        <object></object>
    </span>
</a>

Adding to <a> tag:

display: inline-block;
position: relative; 
z-index: 1;

and to the <span> tag:

display: inline-block;

and to the <object> tag:

position: relative; 
z-index: -1
