(chrome:6958): Gtk-WARNING **: 20:57:08.534: Theme parsing error: gtk.css:73:46: The style property GtkScrolledWindow:scrollbars-within-bevel is deprecated and shouldn't be used anymore. It will be removed in a future version
Opening in existing browser session.
As a result the default chromium browser runs instead, which I installed manually for daily use, and the version is 91.0.4472.77 .
It’s not just a warning when the default chromium (say A) in system for daily is running, in this case try to run chromium in node_modules will launch A as the warning shows.
It’s just a warning if no A is running.
What I expect is that by running chromium in node_modules will run itself anyway.
