@this incorrectly applies in TS files in typeToString

[sandersn]

// @strict: true
/** @this {number} */
function nothis/*1*/() {
  this // noImplicitThis error here
}
nothis() // `this` not required to call

Quickinfo at /*1*/, and type baselines, print the type of nothis as (this: number) => void, even in Typescript where the tag should be ignored. But the type checker still has this: any, so I think it's a bug inside typeToString.
