With Stage Manager on iOS 26 the UI description doesn't cover the app, but the background

[odrobnik]

I have an iPad Pro 13-inch (M4) sim with iOS 26.0. The app was launched with simctl, but is not displaying full screen:

Codex via VSC:

$ bash -lc 'axe describe-ui --udid ED25E0A3-1A88-4A3E-A6A6-5DEF2AB4199E'
objc[56872]: Class FBProcess is implemented in both /System/Library/PrivateFrameworks/FrontBoard.framework/Versions/A/FrontBoard (0x2b1c1a460) and /opt/homebrew/Cellar/axe/1.1.1/libexec/Frameworks/FBControlCore.framework/Versions/A/FBControlCore (0x10512e2f0). This may cause spurious casting failures and mysterious crashes. One of the duplicates must be removed or renamed.
[
  {
    "AXFrame" : "{{0, 0}, {1032, 1376}}",
    "AXUniqueId" : null,
    "frame" : {
      "y" : 0,
      "x" : 0,
      "width" : 1032,
      "height" : 1376
    },
    "role_description" : "application",
    "AXLabel" : "DockFolderViewService",
    "content_required" : false,
    "type" : "Application",
    "title" : null,
    "help" : null,
    "custom_actions" : [

    ],
    "AXValue" : null,
    "enabled" : true,
    "role" : "AXApplication",
    "children" : [

    ],
    "subrole" : null,
    "pid" : 64253
  }
]

And here it is stuck, because describe doesn't see the app in the middle of the screen.
