[bug] client certificate is not used in electron

[lonk]

Hi !
I'm using socket.io over https, using client certificates.
Inside the browser, everything works fine: the client certificate of the browser is used properly by socket.io-client.

Inside Electron, I import the client certificate using importCertificate.
Using axios, the certificate is sent, but not using socket.io-client: the certificate isn't sent, and I get a 400 error (the SSL certificate error) while polling.
(engine.io-client:socket socket error {"type":"TransportError","description":400} +15ms)

Any idea to tell socket.io-client to use the electron client store ?
Thank you !
