In vscode when commenting a block that already contains other comments will display the inner comments as strike-trough lines, also grayed out.
I'm not sure if this was an option or a plugin I've installed or a native behavior, but I couldn't find a way to disable this behavior.
Example
/* function helloFn() {
// this is a comment within my function
return "Hello"
} */
The inner comment will be displayed as // this is a comment within my function.
This is true wether I use an outer comment block or a line by line comment.
As soon there is a comment within a comment it will trigger this behavior.
Q: How to disable this?

Thanks to Mark's comment I've used
