Template literal types not giving autocomplete suggestions

Code

        type autocomplete = `meeting`;
        type noAutocomplete = `meeting/${number}`;
        const val: noAutocomplete = 'meet';

Expected behavior:
Beginning to fill out a string on a template literal type will give a useful autocomplete suggestion, like filling it out with a string literal type.
Actual behavior:
In VSCode, there is no autocomplete suggestion and in the TypeScript Playground the suggestion is incorrect.

Inizia riproducendo il comportamento del completamento automatico dei template literal dal link Playground fornito e dall’esempio TypeScript 4.1.2 in VSCode. Confronta i suggerimenti per meeting e meeting/${number}; il lavoro è completato quando quest’ultimo fornisce un completamento utile durante la digitazione.
