@RequiresApi(Build.VERSION_CODES.O)
fun SemanticsNodeInteraction.captureToImage(): ImageBitmapCaptures the underlying semantics node's surface into an ImageBitmap.
This can be used to capture nodes in a normal composable, as well as across multiple roots. Popups and Dialogs (if API >= 28) are specific cases of this, where they can be captured together with their anchor.
For example, selecting the root node (via onRoot()) when a popup or dialog is present will detect multiple roots. In this scenario, the resulting image is cropped to the combined bounding box of all nodes across the different roots. If a Dialog is present among the roots, the image is cropped to the window's visible display frame.
