Problem: Fast context for msg_show event inhibits vim.ui_attach from
displaying a stream of messages from a single command.
Solution: Remove fast context from msg_show events emitted as a result
of explicit API/command calls. The fast context was originally
introduced to prevent issues with internal messages.
