String literal rename doesn't work in object unions

String literal rename

Code

type Actions = { type: 'one', payload: number } | { type: 'two', payload: boolean }
const q: Actions = { type: 'one', payload: 1 }

Expected behavior:
Renaming of values of 'type' fields should also rename the value in actual variable. For example if I rename 'one' in the type Actions TS should also rename the value of type field in q variable, and vice versa.

Actual behavior:
Looks like renaming doesn't start at all

It seems, renaming the key works

@aspirisen Could you provide steps to reproduce?

I think this could be quite a priority, a great number of people use typed actions/events (in redux, ect). They just don't know that it could be refactored without pain and additional replacement work.

@aspirisen try this workaround

interface A1 { type: 'one', payload: number }
interface A2 { type: 'two', payload: boolean }

type Actions = A1 | A2

const q: Actions = { type: 'one', payload: 1 }
