- Improved performance by batching simulatenous node edits, including metadata updates when dragging many selected nodes together. - Updated Vue to new version, allowing us to use `defineModel`. - Fixed #9161 - Unified all handling of auto-blur by making `useAutoBlur` cheap to register - all logic goes through a single window event handler. - Combined all `ResizeObserver`s into one. - Fixed the behaviour of repeated toast messages. Now only the latest compilation status is visible at any given time, and the errors disappear once compilation passes. - Actually fixed broken interaction of node and visualization widths. There no longer is a style feedback loop and the visible node backdrop width no longer jumps or randomly fails to update.
