Change looks good but please add test similar to tests/cases/fourslash/codefixEnableExperimentalDecorators_blankCompilerOptions.ts for jsconfig one.

Just as a heads up, your commits don't seem to be associated with your GitHub account. While this isn't technically a problem, you might care if you want more appropriate attribution. You can either make sure your GitHub account is associated with the email address you're using for your commits, or rebase and amend your commits to fix the author name and email.

If you don't care about any of this stuff, I can always just pull in the changes.

@DanielRosenwasser Thanks for response! Actually it's not a problem for me, but for future requests I will change my email for associating account and commits.
