"items" can become empty after f8 ?

Lines 98 to 112 in 9eb5bec

	while items:
	if isinstance(bpy.context, _RestrictContext):
	break
	try:
	text = items.pop()
	scrollback(c_dict, text=text, type=type)
	ok = True
	except RuntimeError:
	ok = False
	break
	if not ok:
	if text:
	items.insert(0, text)
	return delayed_scrollback("\n".join(items), c_dict, type)

in that case the while loop is never entered, and the line below it if not ok will throw a

  File "C:\Users\USER\AppData\Roaming\Blender Foundation\Blender\2.82\scripts\addons\run_in_console.py", line 107, in scrollback_append
    if not ok:
UnboundLocalError: local variable 'ok' referenced before assignment

or maybe

 while items: 
     if isinstance(bpy.context, _RestrictContext): 
         break 

is what causes ok to be non-existent when line 109 is executed after f8
