Steps to replicate the issue (include links if applicable):
- Make a mapframe with JSON to display markers and lines.
- Put four markers on opposite sides of the antimeridian
- Marker 1 at 173, 1.5
- Marker 2 at -173, 1.5
- Marker 3 at 187, -1.5 (outside of domain)
- Marker 4 at -187, -1.5 (outside of domain)
- Draw 5 latitude lines
- Line red 1: 175 to 185 at 1.0 N (escapes Eastern Hemi)
- Line red 2: 175 to 179.99 and -179.99 to -175 at 0.0 N (following advice https://datatracker.ietf.org/doc/html/rfc7946#section-3.1.9)
- Line red 3: -185 to -175 at 1.0 S (escapes Western Hemi)
- Line blue 4: 175 to 179.99 and 180.01 to 185 at 2.0 S (escapes Eastern Hemi)
- Line blue 5: 185 to 180.01 and 179.99 to 175 at 2.5 S (Line blue 5 reversed)

What happens?:
Markers 1 and 2 display. Markers 3 and 4 do not.
Line red 1 displays left half.
Line red 2 displays entirely.
Line red 3 displays right half
Line blue 4 displays left half.
Line blue 5 displays left half.
Click on the map to bring it up in new window.
Markers 1 and 3 show. Markers 2 and 4 do not.
Line red 1 displays entirely.
Line red 2 displays left half.
Line red 3 disappears.
Line blue 4 displays entirely.
Line blue 5 displays entirely.
(Missing pieces can be found by zooming out.)
Different but similar results if longitude attribute is changed from 179 to -179.
What should have happened instead?:
First, the mapframe display and the display when clicked should be consistent; they are not.
Second, Line red 2 follows the GeoJSON spec, so it should display correctly. Also, Markers 1 and 2 should display correctly because they are within a reasonable domain.
When the clicked display is zoomed out to display more than one circumference, it should duplicate the symbols.
