Sorry to open an old case, but this also happened exactly the same on Electron version ^19.0.4

As far as I see, the webContents/Preferences are deduced from the renderer process id. With affinity, we can have several pages hosted in the same renderer process id. So currently, it returns always the same webContents for pages sharing the same process. This design must be changed and we have to get the webContents for a specific page (rendererFrame?).
