Error in qt5.natvis: “identifier "$T1" is undefined”

Repro:

1. Have Visual Studio 2015 with Qt Visual Studio Tools 2.2.2 set up to use Qt 5.10.1 x64 (in case it matters).
2. Using the Add New Project wizard, add a new Qt console app project with all defaults (maybe except the project name).
3. Replace the source code with the following: 

   #include <QStringList>
   void main() { QStringList l; }
   

4. Build the x64 Debug configuration.
5. Set a breakpoint in the main() line, run the app in the debugger.

Expected: when the breakpoint is hit, there are no natvis errors in the Output pane.

Actual: when the breakpoint is hit, there is the following error in the Output pane:

Natvis: C:\USERS\MY_ACCOUNT\APPDATA\LOCAL\MICROSOFT\VISUALSTUDIO\14.0\EXTENSIONS\4KF5SRFQ.U2A\Visualizer\qt5.natvis(399,28): Error: identifier "$T1" is undefined
