• Fix a performance regression when bundling code with deeply nested property calls (#6565)

• #6565: Fix path-dependent explosion when including call arguments of reassigned variables (@lukastaegert)

• #6171 7843bd5 Thanks @dylans! - Moving whole lines by dragging or cutting no longer adds an empty line. Whole top-level blocks are now moved as blocks. Nested content, like list items and table cells, is moved without its trailing line break, so no containers get merged. Dropping text back onto its own selection is now a no-op, and drag-and-drop deletes through editor.deleteFragment, like cut does, so plugins that guard deletion apply to both.
