Bug report #12622
In virtual fields $area function computes always values using "None/planimetric" ellipsoid

in QGIS master area calculations seems to be (finally) sorted out/fixed. Anyway it seems that when computing $area in Virtual Fields then the None/planimetric" option for the ellipsoid regardless what the one is configured in the project properties.
After doing some reading, i think i will file this problem as an issue:
I have a new shapefile layer in CRS 3857, in a project that has the same CRS. Under project properties, the measure tool is on ellipsoid WGS 84.
When i use the normal field calculator to create a new field for the layer and use the function "$area", the fields get filled with the correct values.
Now when i use the field calculator to add a virtual field with the function "$area", the values in the field represent the area value of the features calculated without ellipsoid (None/Planimetric).
I suppose it's similar or related to issue #12057
