Specificationhttps://dom.spec.whatwg.org/#shadowroot-clonable Summary This enables individual control over whether a shadow root is clonable (via standard platform cloning commands such as `cloneNode()`). By default, declarative shadow roots are clonable. Imperative shadow roots can now be controlled via a parameter to `attachShadow()`. Blink componentBlink>DOM>ShadowDOM <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EDOM%3EShadowDOM> Motivation None Initial public proposalNone Search tagsdeclarative shadow dom <https://chromestatus.com/features#tags:declarative%20shadow%20dom> TAG reviewNone TAG review statusNot applicable Risks Interoperability and Compatibility This is a slight change in behavior, which poses a very small compat risk. Prior to this feature, only declarative shadow roots within `<template>` elements would get automatically cloned. With the change, any declarative shadow root, even in the main page, will get cloned. Safari already shipped the new behavior, reducing the risk. I plan to enable this functionality slowly and monitor for breakage and bug reports. *Gecko*: Positive (https://bugzilla.mozilla.org/show_bug.cgi?id=1868428) Shipping soon *WebKit*: Shipped/Shipping ( https://developer.apple.com/documentation/safari-release-notes/safari-17_4-release-notes#Web-API ) *Web developers*: No signals *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?
