Test case

Load this with debug WK:

<body onpageshow="window.print()">
<audio src="">
<script>
    window.print();
</script>

Note: according to the backtrace, this might be a GTK specific issue but I couldn't verify it on another port. It'd be great if someone else could check it.

Backtrace:

ASSERTION FAILED: !m_adoptionIsRequired
../../Source/WTF/wtf/RefCounted.h(45) : void WTF::RefCountedBase::ref()
