Robin Malfait f2c2d3c4e0 Fix incorrect scrolling to the bottom when opening a Dialog (#1716)
* add `?raw` option to playground

This will render the component as-is without the wrapper.

* delay initial focus and make consistent between React and Vue

This will delay the initial focus and makes it consistent between React
and Vue.

Some explanation from within the code why this is happening:

   Delaying the focus to the next microtask ensures that a few
   conditions are true:

   - The container is rendered
   - Transitions could be started

   If we don't do this, then focusing an element will immediately cancel
   any transitions. This is not ideal because transitions will look
   broken. There is an additional issue with doing this immediately. The
   FocusTrap is used inside a Dialog, the Dialog is rendered inside of a
   Portal and the Portal is rendered at the end of the `document.body`.
   This means that the moment we call focus, the browser immediately
   tries to focus the element, which will still be at the bodem
   resulting in the page to scroll down. Delaying this will prevent the
   page to scroll down entirely.

* update test to reflect initial focus delay

Now that we are triggering the initial focus inside a `queueMicroTask`
we have to make sure that our tests wait a frame so that the micro task
could run, otherwise we will have incorrect results.

Also make the implementation similar in React and Vue

* update changelog
