AntiSamy warning with No Sample Content
In AEM 6.3 environment with no sample content , I am only getting copy and group option all others are missing in dialogue. (edit, paste, delete)

Error.log is having following warnings :
org.apache.sling.xss.impl.HtmlToHtmlContentContext AntiSamy warning: The link tag contained an attribute that we could not process. The href attribute had a value of "/libs/cq/security/content/admin.ico". This value could not be accepted for security reasons. We have chosen to remove the entire link tag in order to continue processing the input.
org.apache.sling.xss.impl.HtmlToHtmlContentContext AntiSamy warning: The span tag had a style attribute, "font-size", that could not be allowed for security reasons.
How to resolve this? Please help.
