Describe the issue

The camera controls for the SceneWidget's FLY view control are non functional.
Specifically W,A,S,D do not have any effect on the cameras position.

Steps to reproduce the bug

Run this on Windows using WSL
Full Source code:

import open3d as o3d
import open3d.visualization.gui as gui
import open3d.visualization.rendering as rendering
print(o3d.__version__)
app = gui.Application.instance
app.initialize()

window = app.create_window("FLY Mode Test", 1024, 768)
scene_widget = gui.SceneWidget()
window.add_child(scene_widget)

scene_widget.scene = rendering.Open3DScene(window.renderer)
scene_widget.set_view_controls(gui.SceneWidget.Controls.FLY)
window.set_focus_widget(scene_widget)

def key_callback(event):
    print(f"Key: {event.key}")
    if event.key in [gui.KeyName.W, gui.KeyName.A, gui.KeyName.S, gui.KeyName.D]:
        return gui.SceneWidget.EventCallbackResult.IGNORED
    return gui.SceneWidget.EventCallbackResult.IGNORED

scene_widget.set_on_key(key_callback)

# Create and add a mesh
mesh = o3d.geometry.TriangleMesh.create_box()
mesh.compute_vertex_normals()
scene_widget.scene.add_geometry("box", mesh, rendering.MaterialRecord())

# Frame the camera to view the mesh
bounds = mesh.get_axis_aligned_bounding_box()
scene_widget.scene.camera.look_at(
    bounds.get_center(),
    bounds.get_center() + [0, 0, 3],  # Camera position
    [0, 1, 0]                         # Up direction
)

app.run()

Error message

No error message, just notice the the camera does not move.

Expected behavior

The Camera should move with the WASD movement
