Selecting menuitem Title in menuitem editor starts dragging of menuitem itself.

Steps to reproduce:

1. Enter into channel edit mode.
2. Click on menu item icon
3. Open a menu item
4. Select the title of the menu item
5. Notice menu item starts dragging which is not acceptable.

Use case:Sometimes users have long menu item Title and in case they want to copy-paste the menu item then that's not possible because on selecting the menu item title dragging starts.

So will be nice if we can prevent that.
