windeployqt missing qtwebengineplugin.dll

When I deploy my app using windeployqt tool under 5.8 msvc2015_64, after starting the app, it does not appear, but occurs on the process list.

I've noticed that the problem is related with the Qt5Core.dll, because when I copy this lib manually from the "5.8/msvc2015_64/bin" directory, the app works fine.

This may help:

• MD5 checksum is different for the Qt5Core.dll that is located in "5.8/msvc2015_64/bin" and for that copied by windeploy, but the sizes are the same
• windeployqt output with verbose level 3 prints that "Patching" is executed only for that lib
