This issue tracks the work done to test the performance and resilience of the Directives Hydration mechanism. As this approach requires building up a representation of the DOM of the whole page, we have to make sure that it performs well and does not interfere with third party scripts and styles.

The main branch of this experiment is main-wp-directives-plugin. Make sure you select it when opening a pull request if it is related to this experiment. Note that this is the same branch that we're using to develop the WordPress Directives Plugin!

Please proactively comment on this issue whenever you start working on a new task, get blocked, or finish a task, sharing as much detail and information as possible. Thanks!!
