SmartClient 5.7.1 Patch for SectionStack not filling space freed by hiding sections

[Isomorphic]

In the SmartClient 5.7.1 build, there is an issue with the SectionStack class whereby in some cases, when sections are hidden, the freed space within the SectionStack isn't automatically filled.

This patch will address this issue. It applies to SmartClient 5.7.1 versions only.
