Deeply nested {{rich:dataTable}} can cause rendering issues in its parent {{rich:dataTable}}

This is observed in richfaces 3.3.3, unfortunately the project I am working on is restricted to this version because we have to use jsf 1.2 due to a requirement to be able to run on a java 1.5 application server in future.

For the following description please reference the code I have added to 'steps to reproduce' section.

I created 4 nested datatables (see dataTableIssue.xhtml), where each datatable is used to display an object in the following hierarchy:

{{Farm}}
{{--Field}}
{{&nbsp;&nbsp;--Animal}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--Tag}} 

Each item in the hierarchy has three children (so each farm has 3 fields, each field has 3 animals and each animal has 3 tags). From the code in dataTableIssue.xhtml, I would expect the tables to be displayed as follows:

{{farm1}}
{{--field1}}
{{&nbsp;&nbsp;--animal1}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag1}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag2}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag3}}
{{&nbsp;&nbsp;--animal2}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag4}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag5}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag6}}
{{&nbsp;&nbsp;--animal3}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag7}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag8}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag9}}
{{--field2}}
{{&nbsp;&nbsp;--animal4}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag10}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag11}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag12}}
{{&nbsp;&nbsp;--animal5}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag13}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag14}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag15}}
{{&nbsp;&nbsp;--animal6}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag16}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag17}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag18}}
{{--field3}}
{{&nbsp;&nbsp;--animal7}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag19}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag20}}
{{&nbsp;&nbsp;&nbsp;&nbsp;etc.}}

However, what is actually rendered is the following (i.e. the animals in field1 are not listed):

{{farm1}}
{{--field1 (the animals are not listed for this field)}}
{{--field2}}
{{&nbsp;&nbsp;--animal4}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag10}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag11}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag12}}
{{&nbsp;&nbsp;--animal5}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag13}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag14}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag15}}
{{&nbsp;&nbsp;--animal6}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag16}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag17}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag18}}
{{--field3}}
{{&nbsp;&nbsp;--animal7}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag19}}
{{&nbsp;&nbsp;&nbsp;&nbsp;--tag20}}
{{&nbsp;&nbsp;&nbsp;&nbsp;etc.}}

I can see from the debug that the backing bean has the correct data so I know it's not a data issue.

If I remove the last nested dataTable from the jsf page (marked 'TROUBLESOME TABLE' in dataTableIssue.xhtml), then it will render correctly. For example it will display as:

{{farm1}}
{{--field1}}
{{&nbsp;&nbsp;--animal1}}
{{&nbsp;&nbsp;--animal2}}
{{&nbsp;&nbsp;--animal3}}
{{--field2}}
{{&nbsp;&nbsp;--animal4}}
{{&nbsp;&nbsp;--animal5}}
{{&nbsp;&nbsp;--animal6}}
{{--field3}}
{{&nbsp;&nbsp;--animal7}}
{{&nbsp;&nbsp;etc.}}
