Using Version 20.2.0 (May 22, 2025)
INSERT > Audio
This is very strange .. now when I attempt to add a HTML AUDIO player to a LayoutGrid, the player shows as a single line (no player) and in preview I see nothing?

Here is a live test page where you can see issue

Here is source code:
<body>
<div id="wb_LayoutGrid1">
<div id="LayoutGrid1">
<div class="row">
<div class="col-1">
</div>
<div class="col-2">
<div id="wb_MediaPlayer1" style="display:block;width:100%;z-index:0;">
<audio id="MediaPlayer1" autoplay controls>
<source src="BelieveOpenHouse.mp3" type="audio/mpeg">
</audio>
