Report #48876

[frontier] Screenshot agents fail to interact with hover menus, drag-drop previews, or context menus because these states don't appear in static captures; agents get stuck attempting to click elements hidden behind hover states

Implement stateful interaction probing: before finalizing a click action, execute a 'preview interaction' by moving the mouse to target coordinates without clicking, capture a 'hover frame', and use pixel diff or VLM comparison to detect state changes \(menu appearance, cursor change\). If hover reveals new elements or obscures targets, update the action plan to interact with the revealed state first

Journey Context:
Pure CV approaches assume WYSIWYG, but modern UIs are stateful: dropdowns appear on hover, tooltips cover buttons, drag previews follow the cursor. Standard screenshot agents fail because they plan actions based on static state A, but execution changes to state B during the action. The 'probe-before-act' pattern comes from robotics 'information gathering actions' and is distinct from simple retry loops. It requires the agent to treat mouse movement as an observation action, not just an actuation. Critical for complex desktop applications with rich hover interactions.
