Description
Since some days with current 3.1 master if I start a fresh project and load OSM as xyz it will not zoom to 'world', but stays on 0,0 scale 1:1700.
Meaning I'm seeing a nice blue screen and I have to either zoom out a couple of times, or use 'Zoom to Layer'.
Before I always zoomed to the world extent of osm.
To reproduce:
- remove ~/.local/share/QGIS to be sure you have a clean profile
- start QGIS (and not it starts in EPSG:4326)
- from browser open osm layer from XYZ tiles
- see bleu screen as in attached image
Note that if you then resize the screen,
Remove the osm layer
Load the osm layer again: all is fine: you will see the world.

Note: I use proj5 here (Debian sid with recent proj patch). That could be the problem. I do not see it on Windows/OSGeo4w (using proj4).
Hopefully somebody else using proj5 can test?
Note that my messages are flooded with:

and in debug msg in terminal I see:

Unfortunately, I still cannot test it on Mac as proj5 formula generates a build errror. I will do as soon as the build error goes away.

I can confirm on Debian Buster (today it got the 5.0.0-3 patch from experimental; not tested with older proj).
