ERROR TypeError: Cannot read property 'style' of null

Hi. Can you provide a way of reproducing the issue or share some code maybe on stackblitz or similar?

@RaschidJFR I am also getting this error with v3.0.0-dev of this library, Angular v13 and Ionic v6.
The code I am using is really simple:

<ion-header
    parallax
    imageUrl="/assets/images/some-picture.jpg"
    maximumHeight="300"
    expandedColor="#FFFFFFFF"
    titleColor="#FFFFFF"
>
    <ion-toolbar>
        <ion-title>Event</ion-title>
        <ion-buttons slot="end">
            <ion-button
                color="dark"
                fill="solid"
            >
                Continue
            </ion-button>
            <ion-button id="menu-btn">
                <ion-icon slot="icon-only" ios="ellipsis-horizontal" md="ellipsis-vertical"></ion-icon>
            </ion-button>
        </ion-buttons>
    </ion-toolbar>
</ion-header>

<ion-content class="ion-padding">
    <h3>Foo Bar</h3>
    <p>Foo bar baz.</p>
</ion-content>

The error happens on this line and it's not triggered every time. Maybe the timeout should be increased?

Also, any idea why buttons with slot="end" are shown in the start of the toolbar and why those same buttons disappear when I have other buttons in slot="start"?
