debugging a CEF browser instance

After a very long time away from Livecode, I'm trying to get back into it.

On 8.1.4 in the Windows IDE I have a browser instance where a standalone
web page with some Javascript code is not working.  The same page works if
I load it into Chrome.

So, I thought there might be a way to display the console of the browser
instance, but I can't find a "chrome://..." command to do that. The most
information I can get back from the browser instance is this:

"C:/Program Files (x86)/RunRev/LiveCode Business 8.1.4/LiveCode Business"
--browser-subprocess-path="C:\Program Files (x86)\RunRev\LiveCode Business
8.1.4\Externals\CEF\libbrowser-cefprocess.exe" --no-sandbox --lang=en-US
--log-file="C:\Program Files (x86)\RunRev\LiveCode Business
8.1.4\debug.log" --log-severity=disable --locales-dir-path="C:\Program
Files (x86)\RunRev\LiveCode Business 8.1.4\Externals\CEF\locales"

So, I created a .cmd file where I launched the livecode .exe, passing in
different values for


but no alternative parameters in the .cmd file appear to be taken up (i.e.
it looks like these CEF browser parameters might be hard-coded into the LC

I'm thinking there must be a way to debug CEF browser instances, but a
search through the mail list didn't turn up anything that appeared relevant.

Any suggestions?
