Hi @nemesifier

This PR improves how map options are initialized in LeafletCoordSys.create.
It now creates a new object starting with a default { worldCopyJump: true } and then applies or overrides any user-provided settings.
This helps ensure better user experience when panning across ±180° longitude (antimeridian) by enabling worldCopyJump by default.

Could you add a simple test which asserts that this worldCopyJump option is set to true?

This will protect us from the possibility that someone removes this by mistake in the future.

Thanks for the review! The tests are now passing locally after adjusting the map options and cleaning up the formatting.
Please let me know if any further changes are needed.

While running all tests, a couple of existing browser tests failed — for example:

• Chart Rendering Test › render floorplan map without console errors
• Chart Rendering Test › render wifi clients example without errors
  These failures seem unrelated to my change, since they also occur when my new test file is removed.

My new test passes successfully and confirms that worldCopyJump is true by default.

Could you please confirm if these browser tests are known issues, or should I look into them further?

[nemesifier]

LGTM, I'll just rename the test file for consistency.

Upon closer inspection, I see there's a test which is failing for real (not a false positive).

I am leaning towards a simpler approach, see #466.

Thanks for contributing!

Thanks for the feedback!
I’ll take a look at #466 to see the simpler approach.
Glad I could help confirm the issue and contribute to the discussion.
Appreciate your time and guidance!
