Specification

https://drafts.csswg.org/cssom/#the-cssimportrule-interface

Summary

Allow CSSImportRule.styleSheet to be nullable. The styleSheet attribute in CSSImportRule can be null if there is no associated CSS style sheet.

Blink component

Blink>CSS

Motivation

The styleSheet attribute can be null if there is no associated CSS style sheet. styleSheet has become nullable since supports() was supported in @import. If a <supports-condition> blocks the application of the imported style sheet, the UA must not fetch the style sheet. Plus, it must return null for the import rule’s CSSImportRule.styleSheet value.
