"supressWhileTypeErrorsPresent" not working.

I don't have any tslint extensions running.
I am on VSCode Stable Version 1.18.1
package.json:

{
    "devDependencies": {
        "tslint": "^5.8.0",
        "tslint-config-prettier": "^1.6.0",
        "tslint-language-service": "^0.9.6",
        "typescript": "^2.6.2",
        "worker-loader": "^1.1.0"
    }
}

[tslint] errors are still displayed even when there are [ts] errors above them.

It's because 0.9.7 was not published. I have published now. Please retry.

Oh, sorry.
Now it works, but not all [ts] errors prevent [tslint] errors.
A true type error, such as Type '1' is not assignable to type 'string | null'. hides it.
But a broken syntax (but still [ts]) error like Expression expected. (I deleted the 1) lets them through.
Is that how it is supposed to operate?
