    • Write a simple test on browser. roc suggests that we should fix both in this bug.
      • Bug 1: An extra "span" node is created for text after attaching a file, so an extra level in frame tree is created too. This causes the mis-calculation for end caret position.
      • Bug 2: If the last child is a TextNode with no frame, the caret's position may go wrong as well
    • Add recursive call to find the right caret frame and caret offset. Fix try failures.
