Description Keanu Lee 2017-11-07 17:11:09 PST
Per the spec https://drafts.csswg.org/css-scoping/#slotted-pseudo, the ::slotted() selector should only be applied to elements after flattening.

Example: https://jsbin.com/ruwesaj/edit?html,output

The following style:

::slotted(.hide) {
  display: none;

should not apply to the intermediate:

<slot class="hide"></slot>

Yup. That bug is now not to be fixed given the latest discussion at CSS WG: https://github.com/w3c/csswg-drafts/issues/5482

This is working now.
