When rendering (first attachment) <div plaque><div><h1>Ensemble Subcommands</h1></div></div> Firefox correctly replaces the space with a linebreak, but it does NOT recalculate the width of the H1 element

I expect the final rendering to resemble this (second attachment) <div plaque><div><h1>Ensemble<br>Subcommands</h1></div></div> but it doesn't.

Hi, do you have a URL for the page

No link, but this reproduces the behavior -- note: the role of display flex:

 <style>
   html { background: black; }
   body {
     background: white;
     font-family: "Lucinda Sans", LucindaSans, sans-serif;
     margin: 0 auto;
     max-width: 33.88cm;
   }
   div.slide { border: 0.75pt dashed black;
     height: 540pt; width: 960pt; }
   div.plaque {              display: flex;            }
   div.plaque > div { padding: 0 2cm; }
   div.plaque h1 { font-size: 72pt; }
 </style>
 <div class=slide>
   <div class=plaque>
     <div style="background: red;">
       <h1>Ensemble Subcommands</h1></div></div></div>
 <div class=slide>
   <div class=plaque>
     <div style="background: green;">
       <h1>Ensemble<br/>Subcommands</h1></div></div></div>

Maybe someone else will know. Upload your pages here and see what it thinks about the code.

As to somethings you have to find a moz hack to get it to do what you want.
