(TS) Eliminate already-listed cases in switch-case autocomplete dropdown

[mk360]

Search terms: switch, switch case, autocomplete, autocomplete switch case

Considering this example:

type MultiplePossibilities = 'a' | 'b' | 'c' | 'd';
let str: MultiplePossibilities;

// ...

switch (str) {
  case 
  break;
  case
}

When filling the first case, I receive a suggestion from the autocompletion with a selection ranging from a to d. Which makes sense, since it's the first case and there's nothing before it. However, if I choose a in my first case and then move onto other cases, the autocompletion dropdown still suggests a.

The problem is that it makes me lose track of what cases need to be covered, especially since the IDE doesn't raise any warning in case (no pun intended) I added a case I already had covered. This can be especially bothersome in a sufficiently big template literal type.
