typeIn not properly handling decimal places

I have the following test:

```ts
test('number type input accepts decimal values', async function (assert) {

await render(

);

const input = this.element.querySelector('input') as HTMLInputElement;

await typeIn('input', '1.03');
assert.strictEqual(input.value, '1.03', 'allows decimal values');
});
```

and it returns:

```

Indicating an issue with the way that typeIn handles number inputs with decimal places. I cannot repeat this failure between Chrome and Firefox. Only within the test suite. Using `fillIn` instead allows for the test to pass. But `typeIn` should also work. If I had to guess the order in which events are fired may be off when using `typeIn`. I'll need to look into it further.

Start by running the supplied number-input test in the test suite and compare its behavior with fillIn. Trace the typeIn entry point and its event handling for an input with step="0.01" and value "1.03". Done means typeIn preserves the complete decimal value consistently in the test suite, including the reported Chrome case.
