Safari only: x-model does not detect an "autocompleted" input change

[calebrunion]

I use x-model to disable a form's submit button until its related fields have values.

The following code used to work in V2 across modern browsers. But in V3, it breaks when you autocomplete an input in Safari (macOS and iOS). However, it continues to work as expected in Chromium & Firefox.

<form x-data="{ email: '' }">
    <input type="text" name="email" x-model="email" autocomplete="email">
    <button x-bind:disabled="!email" type="submit">Sign Up</button>
</form>

Note: This bug is only for the autocomplete case; x-model will detect change when you simply type in the input.
