Nice improvement 👍

I have a question here, suppose the current map lng bounding is [-170, 181], it is [-170, -179] after wrapping. It will return

{
  right: -179,
  left: -170,
}

The query would be

{
  bottom_right: {
        lon: -179,
        lat: ...,
      },
      top_left: {
        lon: -170,
        lat: ...,
      },
    };

Is this what OpenSearch expecting?

@ruanyl Sorry, do you mean will OpenSearch accept similar to following query or not

{
  "DestLocation": {
    "bottom_right": {
      "lon": -176.8581559092076,
      "lat": -38.91257159667413
    },
    "top_left": {
      "lon": -173.24641047835382,
      "lat": 78.53889135857452
    }
  }
}

@VijayanB I mean will OpenSearch return the same results as expected in the bounding box [-170, 181] after the lng been wrapped in such case where bottom_right.lon < top_left .lon?

Yeah. SouthEast will always be greater than NorthWest in Maplibre since we are not wrapping.

if more than one copies are visible, use max bounds
else wrap bounds.

The backport to 2.5 failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-2.5 2.5
# Navigate to the new working tree
cd .worktrees/backport-2.5
# Create a new branch
git switch --create backport/backport-175-to-2.5
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 7eb646e381337fcc9151d0c881b5b0dbe9ca4f14
# Push it to GitHub
git push --set-upstream origin backport/backport-175-to-2.5
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-2.5

Then, create a pull request where the base branch is 2.5 and the compare/head branch is backport/backport-175-to-2.5.
