`show_dash` keeps hanging indefinitely when port is already used. #123

I experienced (plotly-resampler 0.8.0) that a dash app might keep "hanging" indefinitely, when something is already running on the same port, seems to be caused by a dash-werkzeug combination. Will need to further look into this (fyi: @jvdd )

Seems to be related to the werkzeug version, when I switch from werkzeug==2.2.0 -> werkzeug==2.1.0, everything seems to work fine.

Maybe we keep this issue open and adjust the pyproject.toml as a hotfix? @jvdd
