Greptile Summary

Fixed bug where the editor panel's ring selection (currentBlockId) was not being cleared when duplicating or pasting multiple blocks, causing the ring to remain on the original source block.

Changes

• Added logic to clear currentBlockId when multiple blocks are selected after duplicate/paste operations (line 2087-2089)
• Added same logic to the onNodesChange handler for consistency (line 2195-2197)
• Both changes ensure the editor panel ring is cleared when selecting multiple blocks, since only one block can be edited at a time

Impact

This fix ensures consistent behavior across all selection scenarios - the ring selection now properly clears when multiple blocks are selected, regardless of whether the selection came from a duplicate/paste operation or direct user interaction.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The fix adds a simple conditional check that mirrors existing logic elsewhere in the codebase, ensuring consistent behavior. The change is narrowly scoped, addresses a specific UI bug, and follows the same pattern already used in the onNodesChange handler.
• No files require special attention
