Looking for an explanation for why when calling a function within a try-catch with no prefix await it is ignored

Example:

async function foo() {
    try {
        return bar()
    } catch(e) {
        throw new Error('never see this')
    }
}

async function bar() {
    throw new Error('only see this')
}

foo().then()

When adding await it does reach catch:

async function foo() {
    try {
        return await bar()
    } catch(e) {
        throw new Error('now this works')
    }
}

async function bar() {
    throw new Error('foo')
}

foo().then()

The strange thing is when calling a function that is not async the try-catch does work with no issues:

async function foo() {
    try {
        return bar()
    } catch(e) {
        throw new Error('now this works')
    }
}

function bar() {
    throw new Error('foo')
}

foo().then()
