When a ui-template widget is dragged onto the editor, it has a default type of Widget (Group-Scoped) and default content, including <template>, <script> and <style> sections.
I can put CSS in the style section and it is applied as expected.
However, if I change the widget type to CSS (Single Page) or CSS (All Pages) the presence of <template>, <script> or <style> tags breaks the CSS.
Shouldn't CSS be accepted in a CSS type template even if it is within <style> ... </style> tags?
