I ran into this also. It had me puzzled.

I think it is because of the containerization (is that the proper description)
A simple LOOKING heading, may be 7 layers deep in Divs

<div class="heading1">

      <div class="heading-contents1">

        <div class="element">

          <div class="element">

            <h1 class="element-title1" id="calibre_pb_0">1</h1>

          </div>

        </div>

        <div class="element">

          <h2 class="element-subtitle" id="calibre_pb_1">THE PHOENICIA HOTEL, MALTA, EARTH</h2>

        </div>

        <div class="heading-image-block">

          <div class="heading-image-size-container">

            <img src="../images/00004.jpeg" alt="" class="heading-image-image" data-amznremoved="mobi7"/>

            <img height="120" alt="" class="heading-image-image1" src="../images/00003.jpeg" width="120" data-amznremoved-m8="true"/>

          </div>

        </div>

      </div>

    </div>

All that for 3 lines (includes an image)


Did I guess the why correct?
