browser (bridge): workaround to fix unicode dumping of JSON:
in Brython 3.11, emoji are broken when dumped/parsed with `ensure_ascii`, and using
`ensure_ascii=False` is not working (see
https://github.com/brython-dev/brython/issues/2331).
This work around this and https://github.com/brython-dev/brython/issues/2332 to make sure
that emoji are transmitted correctly to other tabs.
