Generates a CSS selector for all point elements in a scatter series.
Scatter points carry the highcharts-point class. The element tag may vary
by marker shape (<path> for most markers, <rect> for square markers, etc.),
so we match by class only to handle all cases.
Important Highcharts gotcha: each scatter point is emitted as TWO sibling
elements with the same highcharts-point class — the visible marker and a
duplicate hit-detection tracker that is visibility="hidden". A naive
.highcharts-point selector therefore returns 2N elements and breaks
MAIDR's one-element-per-data-point assumption. We filter out the trackers
via :not([visibility="hidden"]) so only the visible markers are returned.
Note on stability: this is the static (initial render) visibility state.
MAIDR's highlight system queries the selector ONCE during trace
construction and caches the resulting element references, so any later
visibility toggling by Highcharts (e.g. on hover) does not affect the
cached set.
