Placeholder default value seems to be ignored?

On the demo site, the x in the placeholder's default position is not displayed:

I've also noticed that in placeholders, the virtual keyboard is automatically displayed on focus on non-mobile devices, which is different than the usual mathfield behavior.

OK, it's a bit confusing, but it turns out the syntax for default value in placeholder is actually \placeholder[id][default-value]{}

@arnog , I'm trying this out now and it looks like input events aren't firing now when the placeholder value changes. Is this intentional? Is there some other way to capture the placeholder value now?
