Experiments have shown that an electron must be smaller than 10^{-22} meters.

I was looking for quantization mechanism in the paper you linked, but without success - could you briefly explain this mechanism?

But still no clear argument that electron is much smaller then femtometer (?)
Anyway, to better specify the problem, define E(r) as energy in a radius r ball around electron.
We know that E(r) ~ 511keVs for large r, for smaller it reduces e.g. by energy of electric field. Assuming perfect point charge, we would get E(r) -> -infinity for r->0 this way. Where does divergence from this assumption starts?
More specifically: for example where is maximum of E'(r) - in which distance there is maximal deposition of 511keVs energy?
Or median range: such that E(r) = 511/2 keVs.
It is not a question about the exact values, only their scale: ~femtometer or much lower?

The "perfect ball" fairy tale is only to convince public that another experiment reducing boudary for EDM makes sense ...
Electron has huge magnetic dipole moment - is tiny magnet ... is at most cylindrically symmetric.
Zero EDM means only that ... e.g. + - + quadrupole has also zero EDM, but has nonzero radius and is not spherically symmetric.
