sp-tooltip

Expected behavior

Given the below code:

    <sp-icon-help>
        <sp-tooltip self-managed>Help is on the way</sp-tooltip>
    </sp-icon-help>

And given that no focusable element can be found in the parent tree of the sp-tooltip, I expect that the focusable element to end up being the document, and that a warning would be thrown when window.__swc.DEBUG === true so that I am instructed on how to provide an accessible, focusable trigger for my tooltip.

Actual behavior

When window.__swc.DEBUG === true, the search loop is closed and the trigger is the document.
We get the expected warnings in the console.

However, when window.__swc.DEBUG === false, nothing is ever returned from the search loop, ending up in an infinite loop.

While this is a problem resulting from an incorrect usage of self-managed, developers may ignore the warnings in the console, as it does not create a loop in environments where DEBUG is true and end up with the infinite loop in production.

What browsers are you seeing the problem in?

No response

How can we reproduce this issue?

1. In the code below, replace window.__swc.DEBUG with false (or directly in the browser console)
2. Open the Tooltip self-managed storybook
3. Remove the focusable element and replace it with a div
4. Check console
5. See error

Sample code that illustrates the problem

while (!triggerElement?.matches?.(focusableSelector)) {
            start =
                triggerElement.assignedSlot || (triggerElement as HTMLElement);
            root = start.getRootNode();
            /* c8 ignore next 13 */
            if (window.__swc.DEBUG) {
                if (root === document) {
                    window.__swc.warn(
                        this,
                        `Self managed [${this.localName}](https://app.slack.com/client/E23RE8G4F/$%7Bthis.localName%7D) elements walk up the composed tree to acquire a trigger element. No trigger element was found before the document.`,

                    );
                    return root as HTMLElement;
                }
            }
            triggerElement = (start.parentElement ||

                /* c8 ignore next 1 */
                root) as HTMLElement;
        }
        return triggerElement;
