Steps to reproduce:
In RFC8831, it says:
The number of streams negotiated during SCTP association setup SHOULD be 65535, which is the maximum number of streams that can be negotiated during the association setup.
In Firefox, the outbound stream count is currently 256 and the inbound stream count is set to 2048. If a data channel is reopened multiple times (or many are opened at once), the outbound stream count can be reached, and then Firefox will use RFC6525 to negotiate an increase of outbound stream count. This feature is only mentioned in short in RFC8831 and is not defined as a MUST, which means that there are no other browser that currently supports it (or SCTP stacks; Can't find support for it in dcSCTP, Pion, sctp-rs).

Marking this S4 since it doesn't appear to be causing issues in the wild.
