Qt online installer wants to install VC runtimes although they are already installed

When running the online installer with:{{}}

qt-unified-windows-x86-3.1.1-online.exe --verbose

I can see the following message:

Komponenten, die als Abhängigkeiten für 'qt.tools.qtcreator' hinzugefügt wurden:

• qt.tools.vcredist
• qt.tools.vcredist_msvc2017_x86
• qt.tools.vcredist_64
• qt.tools.vcredist_msvc2017_x64

Shouldn't the installer recognize that the packages don't have to be installed because they are already installed?

This prevents installing Qt as a normal user.
