ConditionalUI and LargeBlob fails startAuthentication call

[lmarschall]

Hey,

recently I'm trying to use the largeBlob extension a bit to read and write array buffers. Today I wanted to implement the conditionalui behaviour and everything seemed fine, but I realised my startAuthentication function call stalls, with the following setup:
Maybe someone experienced the same issues.

startAuthentication(options, true)
options:
{ "challenge": "r080oMhX2AV7ROXyoQs0We33VojfXI5SjPaIz-GzhIQ", "allowCredentials": [ { "id": "usE4DPxAkY6DSFC7a6p5mPBDiko", "type": "public-key", "transports": [ "hybrid", "internal" ] } ], "timeout": 60000, "userVerification": "preferred", "extensions": { "largeBlob": { "read": true } } }

Additionally sometimes the following error occurs: "The largeblob extension write parameters can only be used with a single credential present on allowCredentials" although there is only one element in the allowCredentials array present :(
