Measure distances and area tool bugging?

[PennyJClarke]

The measure distances and area tool appears to have a bug when used in Jupyter notebook, has anyone else experienced an issue?

When I click on the map to begin a measurement the screen shifts on each click? This video demonstrates the issue:

This error occurs on the basemap, without having added additional layers, ruling out a projection issue.
I also created a new environment containing only Leafmap, to confirm it was not a package conflict, and the error still occurs.

The use of the measure tool is integral to my use of Leafmap, I thank you for any time, support and guidance you can offer.

This is likely an ipyleaflet issue. Try out the code example below to see if you have the same issue.

Thank you Qiusheng for suggesting I check the above example code. You are correct, that the error is stemming from ipyleaflet. This is very helpful.

I have raised an issue on the ipyleaflet github issues page, however, based on your expertise, could offer any guidance on why this may be occurring and if it is a simple bug to fix? Thank you for your guidance and support.

Closing this one since the bug has been reported at jupyter-widgets/ipyleaflet#1076. There is not much I can do about this. As a workaround, you can try the folium backend using import leafmap.foliumap as leafmap
