So it would be better to change :host's parameter to match only shadow hosts. Instead, implement :ancestor (we need better name for this pseudo class) to have the same behavior as old :host. 98679 1 tasak 2014-01-17 05:04:59 +0000 Currently we have the following idea about "better name" for :ancestor, (1) :shadow-ancestor, (2) :host-ancestor 98694 2 annevk 2014-01-17 11:18:31 +0000 Does :ancestor not match self? Because that is named "inclusive ancestor" in the DOM... (I don't know what :host used to match, sorry.) 106962 3 hayato 2014-05-29 07:17:40 +0000 This should have been addressed in css-scoping spec. Let me close.
