This pull request introduces a mechanism to prevent accidental selection of context menu items immediately after the menu opens, improving the user experience and reducing unintended actions. The main changes involve adding a blocking reference to manage click events, refactoring event handlers to respect this block, and updating component props to pass the blocking state.

Context menu interaction improvements:

• Added a menuBlockedRef to both FlowContextMenu and FlowContextMenuNodes components, which temporarily blocks menu item selection for 200ms after the menu opens to prevent accidental triggers. (packages/ui/components/flow/flow-context-menu.tsx, packages/ui/components/flow/flow-context-menu-nodes.tsx) [1] [2]
• Refactored all menu item handlers (onClick → onSelect) to check menuBlockedRef.current and prevent selection if the block is active, ensuring consistent behavior across all context menu actions. (packages/ui/components/flow/flow-context-menu.tsx, packages/ui/components/flow/flow-context-menu-nodes.tsx) [1] [2] [3] [4]
• Updated prop signatures and usage to pass menuBlockedRef through nested context menu components, maintaining the blocking state throughout the menu hierarchy. (packages/ui/components/flow/flow-context-menu-nodes.tsx, packages/ui/components/flow/flow-context-menu.tsx) [1] [2]

Code quality and minor improvements:

• Switched to using useCallback for handleNodePlace to optimize performance and ensure consistent function references. (packages/ui/components/flow/flow-context-menu.tsx)
• Minor style adjustment: changed the context menu content height class for improved layout consistency. (packages/ui/components/flow/flow-context-menu.tsx)
