Hi, Changes for Blink have landed and now you can play this by enabling "experimental web platform features" in chrome://flags.
Now I am proposing this as a patch to shadow DOM, at https://github.com/w3c/webcomponents/blob/gh-pages/proposals/ShadowRoot-delegatesFocus-Proposal.md Feel free to comment here, or at github issue tracker. (The full version of the doc also moved to markdown format, at https://github.com/TakayoshiKochi/tabindex-focus-navigation-explainer/blob/master/TabindexFocusNavigationExplainer.md ) On Wed, Jun 3, 2015 at 4:47 PM, Takayoshi Kochi (河内 隆仁) <ko...@google.com> wrote: > Hi, > > (cross-posting mostly the same content to blink-...@chromium.org, sorry > for duplication if you encounter this twice) > > With much feedback from many people, I've updated the design doc. > > https://docs.google.com/document/d/1k93Ez6yNSyWQDtGjdJJqTBPmljk9l2WS3JTe5OHHB50/edit?usp=sharing > Thanks all who have shared thoughts and experience with me. > > The biggest change is that "tabStop" property on Element moved to > ShadowRoot, as "delegatesFocus". > > After implementing the spec on Blink, I noticed that even tabStop property > is > on every Element, it has effect only on shadow hosts, which is very > confusing. > So delegatesFocus should make more clear sense on shadow hosts. > > With the new spec, delegatesFocus can be specified via ShadowRootInit > dictionary, > which is a parameter to createShadowRoot(). > > I'll start making changes in Blink immediately. > > For reference, I copied a snapshot of old doc (Mar. 19): > > https://docs.google.com/document/d/1wFXrPYmoqb8-b-rfZdmcVfZt09NaTFyOLvGztdlIPxE/edit# > > Any comment is welcome. > > On Thu, Jan 22, 2015 at 6:38 AM, Domenic Denicola <d...@domenic.me> wrote: > >> Thanks Takoyoshi!
