Re: PmSyntax and editing buttons

If you are using the standard $GUIButtons as shown in the documentation, 
or calling the core functions to insert text, that is insertText(), then 
it "should" work. Try it on the WikiSandbox:

   https://www.pmwiki.org/wiki/Main/WikiSandbox?action=edit

If it doesn't work for some reason, it may be a bug or an omission and 
I'd be interested in tracking it and fixing it.

Now, if you have custom functions that insert code by directly 
manipulating the text.value property, after doing that you also need to 
trigger one "input" event:

   var evt = new Event('input');
   document.getElementById('text').dispatchEvent(evt);

Unlike other DOM elements, changes in textarea value cannot be detected 
by a MutationObserver. The only other option I know and even used at 
some point, is to check the value every 50-100 milliseconds. This uses 
up a lot of CPU and battery, so I removed it.
