[Edit in Place] count points in the polygon does not work

[pigreco]

The Count Points in Polygon algorithm works fine, but when used with Edit in Place it doesn't work, i.e. it doesn't add in the field with the count.

How to reproduce it:

1. add two layers, one polygonal and one point;
2. from the processing tools, activate Edit in place and start it;
3. insert the polygon as the first layer and the points as the second;
4. launch the algorithm;
5. when opening the attribute table of the polygonal layer there is no field with the count.

OSGeo4W64 Win 10 64

Even with a clean profile it doesn't work!

I confirm, on QGIS 3.16 and 3.14.0,

@pigreco interesting, here on 3.16 there is no such tool when activating the "edit features in place" option

Is modifying the fields even supported by the current implementation of in place editing? Because if not, then the bug is that the algorithm is flagged as supporting in place edits while it shouldn't!

According to what I read in the docs, it shouldn't be listed if it adds fields to the existing layer. Unless rules have changed and docs needs update.
