Current Behavior / Expected Behavior

You can see the problem in the Content App v16.x, bs4/Content/Text and Image.Part-Image.cshtml line 35

 33 <figure class='@(imgItem.Presentation.ImageLightbox != false ? "effect-zoom" : "")'>
 34   @if (Text.Has(pic.Alt)) {
 35     <figcaption class="pt-1 px-4 pb-4 text-white">@pic.Alt</figcaption>
 36   }
 37   @pic
 38 </figure>

Or the bs5 version.

Since on Line 18 in .Picture(), sets imgAltFallback: imgItem.EntityTitle, when you get to line 35 above, the fallback has already set pic.Alt to the title. So you unexpectedly get a caption over the image, repeating the content's Title.
