     * Finds the trigger element for a self-managed tooltip by traversing up the composed DOM tree.

     * Self-managed tooltips automatically bind to their first focusable ancestor element.
     * This method walks up through shadow DOM boundaries to find a suitable trigger element.
     *
     * A trigger element must match the focusableSelector, which includes:
     * - Interactive elements like buttons, inputs, links, etc.
     * - Elements with tabindex (except -1)
     * - Elements with focusable="true"
     *
     * Common scenarios where no trigger element is found:
     * 1. Tooltip is placed directly in document body without a focusable parent
     * 2. Tooltip is nested in non-interactive elements (divs, spans) without focusable ancestors
     * 3. All ancestor elements have tabindex="-1" or are otherwise non-focusable
     *
     * Expected usage: <sp-action-button><sp-tooltip self-managed>...</sp-tooltip></sp-action-button>
     *
     * @returns The first focusable ancestor element, or null if none found
