False negative when exporting using export declaration - multiple declarations in one statement

[demonhue]

There are only two files in the directory exporter.ts and importer.ts

exporter.ts

export let a=5,b=6,c=10;

and importer.ts

import {b} from "./exporter.ts"

then only a is marked as unused export and c is not marked even if its not imported anywhere

Probably the cause is not supporting multiple declarations in one statement:

export let a=5,b=6,c=10;

as opposed to:

export let a=5;
export let b=6;
export let c=10;
