clicking Bold and Italic buttons on empty line has no effect

[analyst74]

This problem can be reproduced on demo.html, open in chrome, click to an empty line, and click bold/italic button. Those buttons are supposed to be highlighted (see tinymce homepage example), but are not.

Just curious, do you see the same effect on this plunker with the latest code?

I don't see the bug you describe.

I'm sorry, I was using an old version of TinyMCE on one of my plunkers. I do see the issue, thanks for reporting.

Looks like this is related to calls to ed.save(). When commenting out that call in the debouncedUpdate method, the button stays active as expected.

A bit more info...

TinyMCE's save method fires an event:

if (!args.no_events) {
  self.fire('SaveContent', args);
}

I'm not sure why, but it's this event trigger which leads to button state resets.

A temporary workaround could be to disable that event:

ed.save({ no_events: true });

But that likely prevents SaveContent listeners we do want from receiving it.
