HTML Drag and Drop API with contenteditable

Using the HTML drag-and-drop API inside or alongside contenteditable regions often diverges from behavior on plain elements: default actions, `contenteditable` hit-testing, and `beforeinput`/`drop` ordering differ by browser. Custom editors must reconcile native DnD with their own selection model.

Empty paragraphs and br handling in contenteditable

Browsers disagree on how empty blocks are represented (<p><br></p>, <p></p>, <div><br></div>) and how Backspace merges them. Editors that normalize on every keystroke can fight the user or create nested spans.
