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()`). Imperative shadow roots can now be controlled via a parameter to `attachShadow({clonable:true})`. Declarative shadow roots can be controlled via a new attribute, `<template shadowrootmode=open shadowrootclonable>`.

Prior to this feature, declarative shadow roots within `<template>` elements would get automatically cloned. With the change, only shadow roots that are explicitly set to `clonable` will be cloned. I believe the usage of the "inside-template" behavior before was minimal, so the risk should be low. 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?

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).
