LC 9.6

I create I browser widget. I add a JavaScript Handler using (set the
javascriptHandlers). Load webpage on an https server. The callbacks to LC
work OK in Win 10 IDE and on Android deployment. On iOS 13 testers report
the JavaScript call backs don't work first time but on subsequent loads of
the page it works OK. This is the initial problem. So I fired up my test
device to see what's going on. This is where it get weird.

My test device is an iPad Mini running iOS 12.4.7 and JavaScript Handler
call back to LC never works. I put some JavaScript "alert"s in the code for
debugging. The alerts never show up but does show on Android and in the IDE.
The alerts also show up in Safari and Chrome on the same 12.4.7 device just
not in the browser widget. I verified that the remaining JavaScript code in
the page is actually running just fine but no JavaScript Handler call backs
or alerts are working.

Could there a plist permission issue? I'm at a loss... Any ideas?
