Support aria-actions attribute. There is a common UI pattern where secondary actions are placed within composite interactive widgets. The aria-actions attribute allows us to expose these secondary action buttons directly for improved discoverability. An example of this pattern is close buttons in tabs. With this attribute, when a screen reader user focuses on a tab, they will be informed that the close button exists. https://github.com/w3c/aria/issues/1440 https://github.com/w3c/aria/pull/1805
