Uploading SVG data urls will result in an errno":-36,"code":"ENAMETOOLONG" #306
Description
SVG data urls are no longer recognized because the regex in isRemoteUrl doesn't take svg+xml as a mime type into account.
The following regex is used in isRemoteUrl:
/^ftp:|^https?:|^gs:|^s3:|^data:([\w-]+/[\w-]+)?(;[\w-]+=[\w-]+)*;base64,([a-zA-Z0-9/+\n=]+)$/
To match SVG data urls it should probably be like this:
/^ftp:|^https?:|^gs:|^s3:|^data:([\w-]+/[\w-]+(+([\w-]+)?)?(;[\w-]+=[\w-]+);base64,([a-zA-Z0-9/+\n=]+)$/
or like this
/^ftp:|^https?:|^gs:|^s3:|^data:([\w-]+/[\w-+]+)?(;[\w-]+=[\w-]+);base64,([a-zA-Z0-9/+\n=]+)$/
because the mime type for an SVG data url looks like this:
data:image/svg+xml;base64,
The current regex will not match because of the + between svg and xml. This means that with the current code the data url for a SVG file is not seen as remote and the whole of the data url is being used as the name of the file.
