Bug description
Despite installing the rust_log_handler using glib::log_set_default_handler(..), some log messages presumably emitted by gtk4 code is still logged only by the standard glib logger. It seems to me all messages should be sent to the installed handler.
See backtrace section below for full output of running the program. The backtrace itself is not the issue, but might help tracing the issue.
