Shouldn't we have more information with something like:?

const tags = []

function browse(element) {
    if (element) {
        const message = target.dataset.sentry;
        if (message) {
            tags.append(`${element.tagName}.${message}`);
        } else {
            tags.append(element.tagName);
        }
        browse(element.parentElement);
    }
}

browse(hint.event.target);
if (tags) {
  breadcrumb.message = `${breadcrumb.message} | ${tags.join('-')}`;
}
