Gets node bound when the FLAG_RETRIEVE_INTERACTIVE_WINDOWS is unset
Since the WindowInfo is null if the FLAG_RETRIEVE_INTERACTIVE_WINDOWS is
unset, we would fail to calculate the node bound correctly.
The reason behind this failure is that the accessibility framework only
tracks windows when the FLAG_RETRIEVE_INTERACTIVE_WINDOWS is set.
As being a short term solution, we could retrieve the transformation matrix
and magnification spec from WindowState, making us have this CL.
However, as a long term solution, we should keep tracking WindowInfo in
DisplayWindowsObserver whether the flag is set or unset and mitigate the
additional system overhead.
Bug: 229379635
Test: atest android.accessibilityservice.cts
atest com.android.server.accessibility
We use a test apk to test the node bound value when the flag is
unset equals to the value from WindowInfo when the flag is set.
