## Summary Fix panic "cannot update workspace::pane::Pane while it is already being updated" when dragging terminal tabs to split the pane. ## Problem When dragging a terminal tab to create a split, the app panics due to re-entrancy: the drop handler calls `terminal_panel.center.split()` synchronously, which invokes `mark_positions()` that tries to update all panes in the group. When the pane being updated is part of the terminal panel's center group, this causes a re-entrancy panic. ## Solution Defer the split operation using `cx.spawn_in()`, similar to how `move_item` was already deferred in the same handler. This ensures the split (and subsequent `mark_positions()` call) runs after the current pane update completes. ## Test plan - Open terminal panel - Create a terminal tab - Drag the terminal tab to split the pane - Verify no panic occurs and split works correctly
