• ModalDialog.vue was recently created to unify behaviour across various modal dialogs, however a tweak to the capture focus logic try and ensure compatibility with tests was implemented incorrectly, resulting in console errors
• Added functionality to store the previously focused element and return focus on modal close
• Removed copy-paste error referencing bootstrap modal which isn't used by ServicePulse modals

Reviewer Checklist

• Components are broken down into sensible and maintainable sub-components.
• Styles are scoped to the component using it. If multiple components need to share CSS, then a .css file is created containing the shared CSS and imported into component scoped style sections.
• Naming is consistent with existing code, and adequately describes the component or function being introduced
• Only functions utilizing Vue state or lifecycle hooks are named as composables (i.e. starting with 'use');
• No module-level state is being introduced. If so, request the PR author to move the state to the corresponding Pinia store.
