Intellisense breaks often for complex/multiple projects when Qt Vs Tools is running

With the current version of Qt VS Tools plugin, Intellisense often stops functioning - forcing us to constantly reload the projects to fix it. Here are the steps to replicate

1) Unzip the attached "Bug.zip"

2) Open "Projects\QtConsoleApplication24\QtConsoleApplication24.sln"

3) Open "main.cpp" - IntelliSense works correctly (no incorrectly detected errors):

4) Wait 1 minute - to make sure any project initialization is done

5) Open "Projects\QtConsoleApplication25\QtConsoleApplication25.sln"

6) Open "main.cpp" - IntelliSense fails:
