Firefox may hide or misplace the caret when moving across contenteditable=true/false boundaries—widgets and embeds inside editors are affected.
In Chromium, programmatic DOM updates (normalization, wrapping, React reconciliation) while the user is typing can move the caret to the end of the contenteditable or to an unexpected boundary—especially when the mutation happens between keystrokes.
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.
Dragging selected content inside a contenteditable region on Firefox can duplicate nodes or leave ghost fragments—different from Chrome's behavior.
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.
