Broken image size #13

Open valtlai opened 5 years ago

Some browsers ignore the image size (set with HTML attributes or CSS) when rendering broken images (Chrome always and Firefox when a non-empty alt text is provided).

Should browsers preserve the image size? Or should we require that when intrinsicsize attribute is specified?

Hi, It seems reasonable to me that we apply intrinsicSize to broken image. I.e., the behavior of broken image is same to normal image. Otherwise, there's a user visible reflow. For instance:

<img intrinsicSize='100 x 50' style='width: 200px;' src='errorImg.png'> text

The first render size of image would be 200 x 100. (intrinsicSize applied). After detecting image error, the image ratio will be set to 1. So the render size of image would become 200 x 200. The text after image would be moved to a new position too.
