Captions not shown in fullscreen

[andruskalkun]

I have simple media-chrome instance, like this. Problem is that when user clicks to fullscreen button, captions are hidden.

<media-controller defaultsubtitles fullscreenelement="wrapper">
		<video id="player" slot="media" src="media.mp4" poster="media.jpg" playsinline>
		  <source src="media.mp4" type="video/mp4" />
		  <track label="English" kind="captions" srclang="en" src="media-english.vtt" default />
		  <track label="Finnish" kind="captions" srclang="fi" src="media-finnish.vtt" />
	  </video>

	  <media-control-bar>
		<media-play-button></media-play-button>
		<media-time-range></media-time-range>
		<media-captions-menu hidden anchor="auto"></media-captions-menu>
		<media-captions-menu-button></media-captions-menu-button>
		<media-fullscreen-button></media-fullscreen-button>
	  </media-control-bar>
</media-controller>

Javascript is loaded with:

import 'media-chrome';
import "media-chrome/menu";

Whats missing?
