Prior to this change,
preload_link_tag
with an image would generate a tag without anas
attribute. If theas
attribute doesn't get set, browsers tend to ignore thelink
tag (confirmed in Chrome), making the tag useless.This change fixes the issue.
After a quick look at the valid values for as in a preload tag, I don't think there are any other ones missing that could be detected from the file's mime type or extension.
