As AsGoodAsItGets pointed out in one of the comments there is a feature request pending on VS Code github which will allow us to do that.
In the meantime I have a workaround:
- Close all open files
- Open Source Control

- Right click on
Changesand chooseOpen changed files. Note that it will open also deleted files.

- Go to
Searchand selectSearch only in Open Editors

Not ideal, but that’s how I search for my console.log leftovers 😉
