Damn, not working for me for some reason!
Can’t figure out why.
Edit: Fix doesn’t work alas.
I had an issue with this card in Chrome where the centre of the tiling was occurring on the upper left such that only that corner was showing any map at all.
I fixed this by adding the line
contain: paint;
just below line 18 of leaflet.css inside the leaflet container.
You’ll need to clear Chrome’s cache & hard reload (Ctrl F5) to see it working again.
Some bug in leaflet rendering of CSS columns in Chrome.
You should report that on the github repository issues page.
It turns out I was wrong about my fix. I still have the map only appearing in the top corner until I clear Chrome’s cache, refresh/hard reload.
I have played a lot with leaflet and it happens with those other apps too occasionally. So I might see if this issues exists in that community first.
