Hi Stephen,
Please send a new email in a separated thread for the intent to ship.
Thanks,
Rego

The new launch process workflow wouldn't let me do an Intent to Ship for
this one, at least not without some as-yet-unknown gate based on this
email. I've filed an issue to get it resolved.
It would be great if the API owners could treat this as an intent to
ship, but I'm also fine resending it with a different title.

Hi Stephen,
Just checking: were you intending to send an intent-to-ship or a PSA?

Specification
https://drafts.csswg.org/css-pseudo-4/#highlight-cascade
<https://drafts.csswg.org/css-pseudo-4/#highlight-cascade>
Summary
With CSS Highlight Inheritance, the CSS Highlight pseudo
classes, such as ::selection and ::highlight, inherit their
properties through the pseudo highlight chain, rather than the
element chain. The result is a more intuitive model for
inheritance of properties in highlights. Specifically, "When any
supported property is not given a value by the cascade ... its
specified value is determined by inheritance from the
corresponding highlight pseudo-element of its originating
element’s parent element."

Risks
Interoperability and Compatibility
The feature is still under implementation in other browser
engines, but the standards are well developed and there is
general agreement on the spec. I think compat risk is very
limited at this time.
/Gecko/: Neutral
(https://github.com/mozilla/standards-positions/issues/548
<https://github.com/mozilla/standards-positions/issues/548>)
emilio@ is active in standards discussions on the issues, but I
am not aware of implementation.

/WebKit/: In development
(https://github.com/WebKit/standards-positions/issues/95
<https://github.com/WebKit/standards-positions/issues/95>) I
have a private email from the Apple engineer tasked with
implementing. I don't want to reveal PI.
/Web developers/: No signals Developer ergonomics is the primary
concern motivating highlight inheritance. See
https://github.com/w3c/csswg-drafts/issues/2474
<https://github.com/w3c/csswg-drafts/issues/2474> for the
initial spec discussion related to the behavior of ::selection.
See
https://bugs.chromium.org/p/chromium/issues/detail?id=1490471
<https://bugs.chromium.org/p/chromium/issues/detail?id=1490471> for an
example of a user seeing unexpected behavior without this feature.
/Other signals/:
Ergonomics
None.
Activation
No. This reflects the already active behavior for ::selection in
Firefox and the already used behavior for ::highlight,
::spelling and ::grammar.
Security
There are no security risks.
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
Devtools supports highlight pseudos and correctly shows the
inheritance chain.
Will this feature be supported on all six Blink
platforms (Windows, Mac, Linux, Chrome OS, Android, and
Android WebView)?
Yes
There are no cross-platform issues with implementation and no
reason to discriminate on platform.
Is this feature fully tested by web-platform-tests
<https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>?
Yes
https://wpt.fyi/results/css/css-pseudo?label=experimental&label=master&aligned
<https://wpt.fyi/results/css/css-pseudo?label=experimental&label=master&aligned> highlight-cascade-* covers
this functionality. There are additional WPT that make use of the feature in

Finch feature name

Non-finch justification
The feature was enabled as experimental way back in M111 and
stayed that way until M116 when it was switched back to test,
and it is back on experimental for M118. Developers have
significant experience with the feature enabled via experimental
web platform features. There is no value to running a finch
trial given the large amount of existing experience with the
feature.
Requires code in //chrome?
False
Estimated milestones
Shipping on desktop 120

Shipping on WebView 120
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).
