Featured image modal: content disappears when changing device orientation

[afercia]

To reproduce:

• emulate a mobile device via the Chrome dev tools
• edit a post in Gutenberg
• click Featured Image > Set featured image in the sidebar
• the "Featured Image" media modal opens
• depending if your initial device orientation is landscape or portrait, click once or twice on the Chrome dev tool "Rotate" button to change device orientation
• once the orientation is "portrait", the whole content of the modal disappears
• ie: the content container becomes totally empty: <div class="media-modal-content"></div>
• change orientation again: still empty
