Intended to fix positioning quirks caused by changing codemirror instance size when you have lines that wrap and cause line height changes. Often caused by editor toolbox expand/collapse. This adds a debounced resize observer to refresh editor layout on size change. Also tweaks toolbox expand/collapse to more consistently set aria attribute. For #3186
