I could imagine someone want to override normal <title>. Also, the less special cases web components stuff has, the better. 101678 2 bugs 2014-02-28 23:36:01 +0000 Though, setting document.title becomes a bit odd if title can be in the shadow dom. 105114 3 jonas 2014-05-05 22:14:13 +0000 Content in the shadow DOM should by default act "like normal". For a <title> that means that if the Document is in the <title>'s parent chain, and there are no <title>s "ahead of it" in document order, then it affects the Document's title. Otherwise it does not. Shadow DOM never has a Document in its parent chain, and so it should not affect the Documents title. If you want to build your own custom <title> element, then you can do that by using the Custom Elements spec and set Document.title. 105116 4 jonas 2014-05-05 22:15:46 +0000 Also note that we should not set the "in document" flag for Shadow content in Gecko. That has a very random set of effects. What effects it has is very Gecko specific and changes over time depending on how we implement various elements. 112022 5 dglazkov 2014-09-23 15:14:37 +0000 *** This bug has been marked as a duplicate of bug 22361 ***
