[release-branch.go1.19] html/template: emit filterFailsafe for empty unquoted attr value An unquoted action used as an attribute value can result in unsafe behavior if it is empty, as HTML normalization will result in unexpected attributes, and may allow attribute injection. If executing a template results in a empty unquoted attribute value, emit filterFailsafe instead. Thanks to Juho Nurminen of Mattermost for reporting this issue.
