There is still something to run into in a Proton at that size.
At higher energy collisions between a Proton and an Electron New particles are "formed over them". The electron then becomes a Pion. It then has "Vanes". The Kaon also has "Vanes". The decays of these can lead to a Muon. With a mass just short of the Pion. But it is a hadron like the Electron. NO size increase. No "Vanes" From A Higher Energy.
?Charge? constant a type of "Vanes". Or space matching "Vanes". Or Schrodinger Cat is never where you look. ?Low Energy Photon?
