Thank you @Andrius and @Nathan, for the info!
Thanks for your input, @Andrius! Where is this javascript_syntax_highlighting_testfile.js?
You are right, as is Olivier. If there is no way to test it, there is no way to fix it. I don't know and don't have Windows Server 2016, so I would also depend on input from those people who would be willing to do the testing. Is it possible in Server 2016 to start BF from the commandline? If so, could you try that and post the output here (if necessary, as text-file attachment)?

What version of Bluefish is in the flatpak, and which in the RPM?
PPA for Ubuntu 22.04 ?
This may be necessary. A new release may come soon.
