I already tried the existing one: it doesn't work with cached objects (e.g. when you press F5) as the code block is on a cached wiki page. The behavior metadata isn't initialized anymore in the cached page.

That is true... but you can still use this behavior. I had the same problem but have solved it with setting the data with JS. Here my code - of course, you have to adapt this:

/**
 * @provides copy-network-path
 */

JX.onload(function()
{
    // Remarkup is cached and can't hold metadata
    JX.Stratcom.listen(
        'mousedown',
        ['network-path'],
        function(evt)
        {
            const node = evt.getNode('network-path');
            const text = node.parentNode.getAttribute('title');
            JX.Stratcom.addData(node, {
                text: text,
                successMessage: 'Path copied.',
                errorMessage: 'Copy of path failed.'
            })
        }
    );
});

mousedown because it will be fired before the click of the copy behavior.


This way your behavior will be slim because you use already codes core components.
