Display issue with selecting dashboard width

Not sure if this is dashboard specific or a general property box issue.

When selecting the width of a dashboard group, the width selection boxes start to wrap after 27 units:

Not too bad and workable in itself, however this also affects dashboard nodes that want to use all that space:

The only way around this issue is to expand the properties windows from it's default width.

the idea of groups was that there would multiple of them across a page so they could automatically reposition if the overall window changes size... so it was never really envisaged that groups would be 27 units wide or greater (1400 pixels etc) - so it is an edge case that isn't handled well.
