--- Comment #4 from Karl Dubost <karlcow at apple.com> ---
Yes probably a couple of tests would help. 
And after quickly checking on WPT, I didn't find anything obvious testing the type attribute on the source element.

Probably testing:


# unknown string
<picture>
  <source type='unknown_type' srcset="something.png 400w, something2.png 800w">
  <img src="working_image.jpg">
</picture>


# unknown string + a known one.
<picture>
  <source type='unknown_type' srcset="something.png 400w, something2.png 800w">
  <source type='image/jpeg' srcset="something.jpg 400w, something2.jpg 800w">
  <img src="working_image.jpg">
</picture>


# empty string
<picture>
  <source type='' srcset="something.png 400w, something2.png 800w">
  <img src="working_image.jpg">
</picture>

# space string
<picture>
  <source type='' srcset="something.png 400w, something2.png 800w">
  <img src="working_image.jpg">
</picture>


# different type
<picture>
  <source type='image/webp' srcset="something.png 400w, something2.png 800w">
  <img src="working_image.jpg">
</picture>

etc.
