We have created a test page using the following demo page as a template. We have found that in our test, and the demo page, you cannot highlight any text in the grid and do a simple copy to the clipboard. For example in your demo, I try to highlight the city Reims and copy it with a right mouse click.

Strangely, other demos do allow you to do what we would like. For example:

Any ideas, seems like we are missing a simple config setting.
Thanks,
