[Bug] Jupyter: region management in InteractiveMap(): always on full map (resolution)

[neteler]

Describe the bug
I have a large map (say, a Sentinel-2 scene) but only want to visualize a small portion.
For that I set the computational region to a map subset. Still InteractiveMap() sometimes crashed (as shown to @wenzeslaus in a video call).

To Reproduce
Steps to reproduce the behavior:

1. Go to grass_testcase_interactiveMap.ipynb.gz
2. Run the notebook
3. See (sometimes) the error in the notebook. Right now I cannot find the python error message any more which I had shown.

However, while running the notebook, in the raleigh_map.add_raster("bigmap") step r.proj is run as follows:

ps aux | grep proj
r.proj input=bigmap@user1 output=bigmap_user1 mapset=user1 location=nc_basic_spm_grass7 dbase=/home/mneteler/grassdata resolution=1.8561528186341438

I got the impression that always the full map is fed to r.proj. This happened with a Sentinel-2 map (cannot easily provide it here as too large).

Expected behavior

InteractiveMap() should ideally not crash. It may be solved by changing the current usage of region management for the r.proj call.
