tsserver crash: Did not expect SourceFile to have an Identifier in its trivia

[Pajn]

TypeScript Version: 3.0.1 (I think, what's included in vscode 1.26.1)

Search Terms:
Did not expect SourceFile to have an Identifier in its trivia

Code

// @ts-check

/**
 * @typedef {{[key in K]: Array<V>} & {total_count: number, offset: number, limit: number}} Paged
 * @template {string} K
 * @template V
 */

Expected behavior:
No crashes :)

Actual behavior:
Crash with:

[Error  - 8:36:05 AM] 'quickinfo' request failed with error.
Error processing request. Debug Failure. Did not expect SourceFile to have an Identifier in its trivia

Reproduced in typescript@3.0.1 (by hovering over K), did not reproduce in typescript@next.
Probably fixed by #26283.
