BigDecimal with scale of more than 3 gets truncated.

See issue defined here: [grails/grails-core/issues/11241](https://github.com/grails/grails-core/issues/11241)
Basically, if your domain object has a BigDecimal with scale of more than 3, the value gets truncated in etc.
I was advised to raise this issue in this project rather than the grails project.
People have indicated a workaround is to implement something in grails-app/views/_fields/bigDecimal/_displayWidget.gsp, but it would be much better if we could fix the actual issue if feasible.

Start with grails-app/views/_fields/bigDecimal/_displayWidget.gsp and compare its behavior with the linked grails-core issue 11241. Reproduce the display of a BigDecimal with scale greater than 3, then verify that the rendered value is no longer truncated.
