Fix hebrew character highlight issue in a special document
There is an image object and text objects in this document, but the character in each text object is reversed.
When rendering, the image object is shown.
However, when highlighting, the text object is selected, resulting in text index issue.
Moreover, the character in the document is in reading order, which is different from normal document.
