This is fixed already on another pull request

... just fix it here too to make tests pass.
Merge remote branch 'origin/github-main' into jean-setup-tempdoc-for-hidewhens
Push datagrid handling down into TemporaryDocument

Only `readInputs` if we aren't getting data from rowdata.
(I *think* this is the right way.)
Update tests for new datetime serialization format

I missed those here.
Merge branch 'jean-BaseField-getFieldValue-default' into jean-setup-tempdoc-for-hidewhens
If we don't have rowdata, we do have to read form inputs

.. but if we do both, we end up stepping on the selection fields in
rowdata (because absent selection fields are removed).
While dealing with a datagrid row, the value may be a string

This feels kludgy to me, but don't know how to improve it at the moment
