Double-click to select text is broken

- For a terminal which is not capturing mouse input
- When the user clicks and drags, it triggers our special drag-and-drop behavior which works great
- But when the user double-clicks, it triggers some underlying text-selection (not ours). It doesn't look like the text selection above, and `Cmd+C` doesn't do a copy of the selected text

未指定文件或测试。首先，在一个未捕获鼠标输入的终端中复现双击，然后追踪 drag-and-drop 行为所涉及的鼠标处理和文本选择路径。完成标准是双击选择符合预期的选择行为，并且 Cmd+C 能复制所选文本。
