Risks


Interoperability and Compatibility

None


*Gecko*: Positive (https://github.com/mozilla/standards-positions/issues/928
)

*WebKit*: No signal (
https://github.com/WebKit/standards-positions/issues/282)

*Web developers*: Positive

*Other signals*:

Security

This is a cross-document (navigation) feature, so designing it we needed to
take care of cross-origin navigation related risks. Since
`navigation.activation` is part of the navigation API, it uses the same
semantics and protections. We only expose things that are otherwise exposed
by the navigation API or in other means.


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?

None


Debuggability

None


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

Is this feature fully tested by web-platform-tests
<https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>
?Yes

Flag name on chrome://flagsNavigationActivation

Finch feature nameNone

Non-finch justification

It's a web-API, exposing it gradually doesn't make sense.


Requires code in //chrome?False

Anticipated spec changes

Open questions about a feature may be a source of future web compat or
interop issues. Please list open issues (e.g. links to known github issues
in the project for the feature specification) whose resolution may
introduce web compat/interop risk (e.g., changing to naming or structure of
the API in a non-backward-compatible way).
None
