Worked on stabilizing Salesforce Shadow DOM integration within the openreplay/openreplay repository by addressing a nuanced issue in custom element detection. Focused on DOM manipulation and frontend development, the contribution involved updating the isCustomElement logic to recognize SLOT-tagged elements as custom elements, which is essential for accurate shadow DOM handling in Salesforce environments. This targeted bug fix, implemented using TypeScript and JavaScript, improved interoperability by reducing parsing errors related to edge cases in element detection. The work demonstrated a careful approach to web components and custom elements, ensuring more reliable integration and smoother frontend behavior for Salesforce users.
