This is important when working with CSMes, where <script> tags will be purged from the page's contents due to security considerations.

Hi @ku1ik ,

The idea of a fit=both param sounds good to me. Would you like to make the change or do you want me to crack at it?

[ku1ik]

You can have a crack at it if you want, although I won't be able to review it for at least few weeks.
