Description of the bug

Get text by page.get_text("dict")["blocks"], the positions （span's bbox ） of regular text and normal symbols are correct. However, the position of the square root symbol is noticeably incorrect. Please refer to the following debug information and the rectangles I redrew on the original PDF page based on the obtained bbox. It can be observed that the bbox positions are off by nearly 1 line-height to the actual positions.

Debug message:
