When contenteditable='false' elements are placed inside a contenteditable container, the cursor may disappear or become invisible in certain browsers, making it difficult for users to determine the text insertion point.
When a parent element has contenteditable="true" and a child element has contenteditable="false", the inheritance behavior is inconsistent across browsers. Some browsers allow editing in the child, while others correctly prevent it. The behavior may also differ when the child has contenteditable="inherit" or no contenteditable attribute.
Analysis of Firefox's inconsistent handling of native Drag-and-Drop operations within editable containers.
When editing content inside an element with `position:relative`, the text caret (cursor) is completely invisible. Text can be typed and appears in the editor, but there's no visual feedback of where the insertion point is located.
After pasting content into a contenteditable region, the caret position does not end up at the expected location, sometimes jumping to the beginning of the pasted content or to an unexpected position.
