Stielhandgranate symbol in Visual Studio 2017

I’ve just updated Visual Studio 2017 to version 15.7.1 at work and see the Visual Studio team has included¬†a new¬†Stielhandgranate symbol beside the line numbers in the code IDE.

Compare that to the original:

German WW2 hand grenade (Stielhandgranate)
German WW2 hand grenade (Stielhandgranate)
