Description
I feel like we must have an issue for this one, but I can't find it.
function invertKeysAndValues<K, V>(map: Map<K, V>): Map</**/
Request completions at /**/
Expected: The type parameter V is provided as a valid completion entry.
Actual: VBArray is the first provided completion entry. This means that a commit character like , after typing in V will commit VBArray as a type argument.
