Unity WebGL + photon server + plugin

Hi,

I'm debugging some weird behavior I see using my photon server + plugin, perhaps you guys know about it.

If I use WebSocket (Not secure), I sometimes get RPCs out of order (which should never happen).

The thing is, if I don't change anything, besides the protocol to WebSocketSecure, or switch to PC platform and use UDP, I dont see this issue anymore?

I'm running the server locally for this test.

I'm using PUN 1.99 / latest on unity side (not PUN 2).
Photon server version: 4.0.28.2962

Can anyone confirm this is a thing?
