Bug js when replacing a audio or video in post editor

[truonght]

When I replace a audio or video in editor, browser console show an error:

Uncaught TypeError: Cannot read property 'indexOf' of undefined
In file wp-includes/js/media-audiovideo.js?ver=4.4.1, line 801:

if ( this.model.get( 'src' ).indexOf( 'vimeo' ) > -1 && ! ( 'Froogaloop' in window ) )

I think we should check this.model.get( 'src' ) !== undefined

Confirmed. This is a bit "hacky" place to be checking the src but don't see a better one for now. It only prevents a preview to be shown in the modal, the video/audio is replaced properly in the editor.

In 36233:

Media: fix undefined error that prevents showing a preview in the media modal when replacing video or audio.

Fixes #35363.
