beforeinput and input events have different inputType values
During IME composition or in certain browser/IME combinations, the beforeinput event may have a different inputType than the corresponding input event. For example, beforeinput may fire with insertCompositionText while input fires with deleteContentBackward. This mismatch can cause handlers to misinterpret the actual DOM change and requires storing beforeinput's targetRanges for use in input event handling.

Selection mismatch between beforeinput and input events
The selection (window.getSelection()) in beforeinput events can differ from the selection in corresponding input events. This mismatch can occur during IME composition, text prediction, or when typing adjacent to formatted elements like links. The selection in beforeinput may include adjacent formatted text, while input selection reflects the final cursor position.

Browser translation breaks contenteditable editing
When browser translation features (like Google Translate) are activated, they manipulate the DOM by replacing text content and injecting elements. This can break contenteditable functionality, causing cursor positioning issues, event handling problems, and IME composition failures.
