double click inside link

[Garry Yao]

1. Load the following content:

   <p><a href="#">link text</a></p>
   

2. Double click on word "text"

• Expected: selected word is highlighted;
• Actual: Link dialog opens.

Expect the double click (open dialog) shortcut only applies when link is fully selected when double clicked, which happens when:

1. Firefox always select the entire link text no matter of link text;
2. Other browsers it's fully selected only when link text has only one single word.
