Enhance the driver.js Support for Elements in #top-layer

[jortega0033]

It seems that driver.js does not fully support highlighting modals and popovers rendered within the #top-layer. Although the elements are recognized, they fail to receive the expected highlighting.

Context:
The #top-layer creates a new stacking context, which affects how this library displays guidance for these elements. This isn't a bug; rather, it's a matter of adapting to the new feature introduced by the #top-layer.

Use Case:
When using driver.js to guide users through interactions in modals and popovers within #top-layer, the lack of highlighting diminishes its effectiveness.

Proposed Enhancement:
Update driver.js to ensure that the elements it highlights are properly rendered within the #top-layer. This change will make them visible and correctly highlighted.

Additional Notes:
I wanted to try moving the elements inside a element to see if it would be rendered in the #top-layer, but unfortunately, I don't have enough time to do so.
