What are some strategies for modifying or overriding inaccessible third-party components without breaking their functionality?

This is often a tricky scenario depending on the level of customization the third-party code offers. We usually recommend using ARIA markup when working with custom widgets. Let's say the third party created a button instead of using a button tag. In this example, adding the recommended ARIA to ensure it has its accessible name, states, properties, and roles properly communicated is the best way to go. Editing this is less likely to break any functionality because instead of removing anything, you added labels to make it accessible.
