Useful3 Signal2
Permission dialogs appear on your machine instead of being lost while the connection recovers.
What's wrong with this entry?
Anonymous. No account, no email.
What
When the remote bridge has writes gated or is rebuilding its transport, a request to show you a dialog is no longer sent over the wire. It is recorded locally and the send call reports failure, so the dialog is served on your machine rather than lost.
Evidence
Not forwarding request_user_dialog while writes are gated / transport recovering (local-only)
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
