Hi, just an update on the feature:

• implementation is complete, tracking bug: https://issues.chromium.org/issues/365046212
• TAG review in progress here: CSS.highlights.highlightsFromPoint API w3ctag/design-reviews#1043
• Spec was written here: https://drafts.csswg.org/css-highlight-api-1/#interactions

Let me know if there's any questions.

The algorithm seems still quite unclear (or I'm missing something obvious).
For example w3c/csswg-drafts#11745

There were also comments in blink-dev about other things being unclear in the specification.

Hi @smaug----, thanks for the feedback, I'm working on updating the spec here to address that issue #11745 w3c/csswg-drafts#11779

Are there other things you think need clarification as well?
