Double Click select wrong area

Now I have a paragraph which has two kinds of node, one is textNode and another is a Node which has a childNode which is textNode, when I Double Click the line which paragraph loacted, I found the whole line is selected but the state’s selection has only one TextNode.

Can you set up a minimal script that shows a schema and document in which this happens? (Also, which browser are you testing on and where are you double-clicking?)

Now suddenly gone, I doubt the browser bug, Thankyou
