PrecompiledHeaders.h include missing in moc after adding new class

A QtMoc entry in the project file(*.vcxproj) after converting the project from "custom build" to Qt/MSBuild looks like this:

<QtMoc Include="ToolboxView.h">
<Define Condition="'$(Configuration)|$(Platform)'=='Debug|Win32'">...</Define>
<ForceInclude Condition="'$(Configuration)|$(Platform)'=='Debug|Win32'">PrecompiledHeaders.h;../../ToolboxView.h</ForceInclude>
<IncludePath Condition="'$(Configuration)|$(Platform)'=='Debug|Win32'">.\GeneratedFiles\$(ConfigurationName);...</IncludePath>
<Define Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">...</Define>
<ForceInclude Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">PrecompiledHeaders.h;../../ToolboxView.h</ForceInclude>
<IncludePath Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">.\GeneratedFiles\$(ConfigurationName);...</IncludePath>
</QtMoc>

 The <ForceInclude ... PrecompiledHeaders.h lines are not missing so the PrecompiledHeaders.h include will be added in the moc file.

But both ForceInclude lines are missing when i add a new class (project tree --> right click --> add --> add Qt class) after the conversion to Qt/MSBuild.

This results in the following error:

error C1010: unexpected end of file while looking for precompiled header.Did you forget to add '#include "PrecompiledHeaders.h"' to your source?

#include "PrecompiledHeaders.h is missing in the generated moc file.

Manually adding the ForceInclude lines in the project file will fix the error.

Reproduce bug:

• convert project (with PrecompiledHeaders) to Qt/MSBuild
• add new class: project tree --> right click --> add --> add Qt class
• build
