This pull request removes some unused or redundant code from the EditorManager, IFramePreview, and Preview components, and fixes a bug in the FormulaControl component that affected the data context for the formula editor. These changes improve the code quality and the preview functionality of the amis-editor.

No more amisStore, no more data bugs
We rip out the code that was useless and old
We fix the formula logic, we make it clear and bold
We are the masters of the editor, we control the preview mode

Why

How

🤖 Generated by Copilot at 121b3c3

• Remove the code that updates the editor's amisStore with the props.store.data from both IFramePreview.tsx and Preview.tsx components to fix a bug that causes the preview to render incorrectly when the data changes (link, link)
• Remove the amisStore property and the updateAMISContext method from the EditorManager class to clean up the unused code and avoid confusion (link, link)
• Modify the getContextData method in the FormulaControl.tsx component to improve the logic of getting the current data context for the formula editor, using the node.getComponent().props.data path as a fallback when the props.data.__super.props.data path is not available (link)
• Add an empty line to the FormulaControl.tsx component to improve the code readability and formatting (link)
