error-image.html

If we load the attached page directly by https://, the size of error image is 100px x 100px, and with a broken image indicator.
Yet, if we download the page and load it by file://, the size is 100px x 0px, and there is no broken image indicator.

Looked into the code, it seems in CachedResourceLoader::requestResource the request of file:// is canceled, because it knows the page is not accessible by checking the file system.
That makes shouldDisplayBrokenImageIcon() return false. So the appearance is different.
