i think issue is it fails to render the minimap after a certain limit , im working on this , if there's something else causing feel free to leave a comment

My initial guess would be that the minimap may not properly respect the minimum zoom level property of the respective background layers. @Darshit42 feel free to investigate this.

i am investigating it, i will checkout it and if im successful i will make a pr

@tyrasd

this is background_source.js

i have made changes in this function so that the zoom size is always valid , is this correct? or do i need to make some other changes too?

this is the output before minimap was not able to render after 200km

if everything's fine should i raise a pr?

@tyrasd i tried running npm test and there are 4 errors which are all due to zooming out which causes minimap to go black , therefore when i fix the issue and remove the upper bound on the zoom extent these errors occur

should i change test cases to fix these errors??
