Before the client authenticates, the standard frame_max is not used. Instead, the limit is a special constant. This is fine for password or x.509 certificate-based authentication but not for some JWT tokens, which can vary in size, and take multiple kilobytes. 8 kB specifically is the default HTTP header length limit used by Nginx. Sounds like this value was good enough for a lot of Bearer headers with JWT tokens. Closes #13541.

FTR, the value can be bumped further via configuration:
