Describe the bug

There seems to be a glitch with the dataset at the antimeridian: to the west of it, at least two polygons are missing, its also sliced in a weird way there. I am currently getting my hands on the orginal dataset, if thats also an issue there.

considering this code:

var land_mask_ee = (ee.FeatureCollection("projects/sat-io/open-datasets/shoreline/mainlands")
    .merge(ee.FeatureCollection("projects/sat-io/open-datasets/shoreline/big_islands"))
    .merge(ee.FeatureCollection("projects/sat-io/open-datasets/shoreline/small_islands")))
    

Map.addLayer(land_mask_ee)

var selected_polygon = land_mask_ee.filterBounds(selector)
print(selected_polygon)

Map.addLayer(selected_polygon, {color:"green"})
Map.setCenter(176,65)


it finds no polygons at the point "selector".


edit: also saw its missing the western part of Wrangel Island and has weird sliver polygons (arrow)

just want to add that in the original dataset at https://www.sciencebase.gov/catalog/item/63bdf25dd34e92aad3cda273 , the polygons are fine, however the sliver artifacts can be seen there as well. (e.g. VerySmallIslands OBJECTID_1 = 20796)
