ReferenceError: SqueezeJS is notdefined[Learn More]

After upgrading to logitechmediaserver-7.9.2-0.1.1552283404.noarch.rpm
which is the latest version compiled in 10 March 2019, I'm still seeing
a blank, turquoise screen with a spinning rosette followed by "Loading
Logitech Media Server..." in the middle of it.

The Firefox console shows the problem to be a ReferenceError:

SqueezeJS is not defined[Learn More] zoogz:9000:3461:3
<anonymous> http://zoogz:9000/:3461

How or where should this be defined?

I'm running Firefox 64.0 (64 bit) on
Linux version 4.20.17-100.fc28.x86_64 (
mockbuild (AT) bkernel03 (DOT) phx2.fedoraproject.org) (gcc version 8.3.1 20190223
(Red Hat 8.3.1-2) (GCC)) #1 SMP Tue Mar 19 17:48:12 UTC 2019
