Live Editor won't start MATLAB R2018a on ArchLinux

I am trying to use Live Editor in MATLAB R2018a on ArchLinux. Attempts to start Live Editor ends with dialogue box showing
"The Live Editor is unable to run in the current system configuration."
Unlike a previous question, I do have libXss and libgconf installed. (This is a fresh MATLAB install and all the required symlinks seemed present.)
Following the Arch wiki I tried executing
>> com.mathworks.mde.liveeditor.widget.rtc.CachedLightweightBrowserFactory.createLightweightBrowser()
on the MATLAB command line, the output is as follows and is rather opaque to me.
Java exception occurred:
com.mathworks.html.BrowserCreationException: com.mathworks.html.BrowserCreationException:

Any suggestions?

For what it is worth, LiveEditor works on R2019b.
I never got around to getting it to work with R2018a, but I guess that is moot now.

The MATLAB Answers post is the question I linked to in my question above, which didn't help.
I will try however the instructions on the ArchWiki; I don't think I have seen them before, so will give it a try next week when I have some time.

If it doesn't, reach out to MathWorks customer support. They provide free install support to anyone with a valid license.

The info on ArchWiki didn't help. I am going to try for a reach and see if things are better with 2019b.
