I came across an issue with Visual Studio 2017. I'm unable to collapse multiline comments, there is no - sign in front of it like with code blocks.

At home it is no issue and I can do this without problems.
Ive looked online and all I can find is people not being able to collapse comments in VS Code. And people who want to collapse everything but the comments, but the comments do get collapsed.

Is it a setting I cannot find?
