When causing _"output oveflow"_ by printing a lot of text, formating breaks. Possible because enclosing tag get flushed.

Suggested solution: clear text formating after _output oveflow_ warning.

### Steps to reproduce

Print a lot of text with different text tags (like [color] or [bgcolor]) to console. For example in _process function.

### Minimal reproduction project

N/A
Item *item = p_item;
	while (item) {
		if (item->type == ITEM_FGCOLOR) {
			ItemFGColor *color = static_cast<ItemFGColor *>(item);
			return color->color;
		}
		item = item->parent;
	}
	return Color(0, 0, 0, 0);
}

			return true;
		}
		for (Item *E : from->subitems) {
			bool layout = _find_layout_subitem(E, to);
			if (layout) {
