3.16 improvement - Consider using the Intersection Observer API instead of doing the calculation manually

Open MathieuLamiot opened this issue 10 months ago • 0 comments

Context Subtask of #6449 The current version of the beacon script identifies "manually" above the fold content (see var intersecting). This could be done with the Observer API directly, and probably be more efficient / accurate. This is not needed for 3.16 but it is a performance enhancement.

Expected behavior

  • Rework the computation of ATF images based on the Observer API instead of a manual check.

Acceptance Criteria

  • NRT of the 3.16 feature: check with QA for the 3.16 test plans and run Rocket-E2e if available.
