Banner not dismissing

Have the same issue when we talk about the re-appearing banner. This happens only if the username of the logged in user includes a “dot” and also triggers an error in the console if the banner is closed.

  1. Are there any other known issues if a “dot” is in the username - e.g. max.muster?
  2. Is there a workaround for new installations to prevent the usage of “dots” or other problematic additional characters when choosing the username (for invite & self-signup)?
