https://github.com/MicrosoftEdge/MSEdgeExplainers/blob/main/highlight/events-explainer.md Specification Spec text pending. IDL is in the explainer here, subject to change: https://github.com/MicrosoftEdge/MSEdgeExplainers/blob/main/highlight/events-explainer.md#proposal Summary Adds pointer event handling to the Custom Highlight API. The Custom Highlight API (see https://chromestatus.com/feature/5436441440026624) provides a way for web developers to style the text of arbitrary ranges. Adding pointer event handling to these highlighted ranges will make them interactive, unlocking features such as a custom spellcheck that shows suggestions when a highlighted spelling error is hovered or clicked. Blink component Blink>CSS <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3ECSS> Motivation The Custom Highlight API (see https://chromestatus.com/feature/5436441440026624) provides a way for web developers to style the text of arbitrary ranges. Adding pointer event handling to these highlighted ranges will make them interactive, unlocking features such as a custom spellcheck that shows suggestions when a highlighted spelling error is hovered or clicked. Initial public proposal https://github.com/MicrosoftEdge/MSEdgeExplainers/blob/main/highlight/events-explainer.md https://github.com/w3c/csswg-drafts/issues/7447 TAG review Pending TAG review status Pending Risks There should not be a compat risk with the existing Highlight API, since this is purely additive. If no event listeners are added to Highlights, they will continue working as they do now. We do have to be careful about changing PointerEvent behavior; for example, PointerEvents currently only have Nodes as their target, so allowing Highlights to be PointerEvent targets could break the expectations of current code. We will need to be mindful of these risks while progressing the design of the feature. Developers can feature-test by checking for the existence of window.HighlightPointerEvent. Interoperability and Compatibility *Gecko*: No signal *WebKit*: No signal *Web developers*: No signals *Other signals*: WebView application risks None Debuggablity We’ll ensure that HighlightPointerEvents are exposed in DevTools’ Event Listeners pane. Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ? No, we'll add WPTs as we prototype the feature and will keep them updated as the spec develops. Flag name HighlightPointerEvents Requires code in //chrome?
