A concrete starting point
Return keyboard focus when a browser dialog closes. Check the case where its opener has been removed and keep the remaining page usable without a mouse.
Define the change
Describe the input, expected output and boundaries that must stay intact.
Inspect the work
Review the proposed edits and any commands before relying on their result.
Check the outcome
Compare actual behavior with the expected result. If a check fails, investigate it before applying more changes.
Browser interactions
A concrete starting point
const previousFocus = document.activeElement;
dialog.showModal();
dialog.addEventListener('close', () => {
if (previousFocus instanceof HTMLElement &&
previousFocus.isConnected) previousFocus.focus();
}, { once: true });The example is a starting point for a real project, not a claim that generated code is already tested. Adjust paths, dependencies and expected behavior to match your application.
