Cannot select text(only in Firefox) in Grid plugins

[sandeepdreddy]

In the first example of the following page
http://dev.sencha.com/deploy/ext/exa...d-plugins.html
when the row is expanded, the text contained in it cannot be selected by dragging the
the mouse in Firefox. This issue is not seen in IE.
Thanks,
Sandeep

I referred to a similar thread, and tried 'position:absolute', but I still see the layout issue.
