I don't have a request in templates for favicon.ico.
In Firefox inspector:
Request cookies are: 'adminer_key', 'adminer_sid', 'tracy-session', 'wire0s', 'wire1s', 'wire1s_challenge', 'wires', 'wires_challenge'.
Stack trace:

I don't know what those are. I did recently install and then afterward notice an odd commit and deleted the module -- https://github.com/FriendsOfProcessWire/FieldtypeLeafletMapMarker/commit/e57e9373e6cccb79fe89dfda00fec117624649f2
has a bunch of empty files? "Remove executable bit from files"? -- Sorry I just realized the permissions changed from 755 to 644...
