Example widgets in the doc do not get rendered

[oscar6echo]

In the doc widget list page the example widgets do not get rendered.
Probably a small bug.
This page is quite useful to have an instant overview of what's available as core widgets.

This seems to be rendering now. Are you still seeing the same behaviour?

Just tested in Firefox and Chrome and still no rendering...
The Chrome console says:
