I got it. If GetFirstFrameInRangeForTextRect() does not find any visible content, it does not return a frame. In that case, we should guess caret position in first visible parent. Then, IME can show its window at least around the editor.
Summary: Avoid warnings in `ContentEventHandler` → `ContentEventHandler` should guess caret rect from parent frames when there is no text
