Expanding PropertyGrid item by a single click.

Hi

I updated the version of WPF Controls to v17.2.0664 from v17.2.0662.

Expanding a PropertyGrid property item by a single click is that not working after updating.
Expanding a PropertyGrid category item by a single click is working.

Is this behavior a bug ?

I want to expand a property item by a single click as in v17.2.0662.

Thanks,
