Report #56037

[frontier] Agents click wrong coordinates when UI elements shift between screenshots due to responsive layouts or animations

Use Set-of-Mark \(SoM\) prompting: overlay numbered masks on UI elements via segmentation models and reference element IDs instead of absolute pixel coordinates

Journey Context:
Absolute coordinates fail on retina displays, viewport resizing, or CSS animations. DOM selectors miss canvas/WebGL elements. SoM provides semantic anchoring that survives visual transformations. The Microsoft Research implementation uses GPT-4V with DETR or SAM to generate masks, then references 'mask 42' instead of \(x,y\).
