Risks

Interoperability and Compatibility

Gecko: Defer (https://github.com/mozilla/standards-positions/issues/811)

WebKit: No signal (https://github.com/WebKit/standards-positions/issues/195)

Web developers: Positive (https://github.com/w3c/manifest/issues/737)

Other signals:

WebView application risks

Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications?

N/A. This feature is not supported on WebView so we will fallback to a supported display mode.

Goals for experimentation

Gather feedback on the API design.

Ongoing technical constraints

Debuggability

chrome://web-app-internals can be used for debugging, and the new manifest field could also be added to the DevTools Application pane.

Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?

No. Initially this will only be available on ChromeOS, but will be expanded to other desktop platforms in the future.

Is this feature fully tested by web-platform-tests?

No

Is it available in CSS media queries?

@media (display-mode: tabbed) { ... }

I have opened https://github.com/w3c/manifest/issues/952 where the same request is made for all overrides.

@Šime: Yes, the feature as currently implemented is exposed as a media query: "(display-mode: tabbed)" works.

We flagged additionally the need to be able to detect whether you're in the special home tab. I'm not sure how you do that (whether it's a media query or some other way) and it isn't mentioned in the explainer. Perhaps Louise can explain (out until next week) if there is a way to do it. However, I checked the basic detection of "am I in tabbed mode" works with a media query.

We aren't ready to start the origin trial in M117 so we are going to run it from M118-123 (inclusive).

No issues, thanks for the update.
