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
line = p_text.substr(pos, end - pos);
		}
		if (line.length() > 0) {
			if (current->subitems.size() && current->subitems.back()->get()->type == ITEM_TEXT) {
				
				ItemText *ti = static_cast<ItemText *>(current->subitems.back()->get());
				ti->text += line;
				_invalidate_current_line(main);
			} else {
				
				ItemText *item = memnew(ItemText);
				item->text = line;
				_add_item(item, false);
			}
		}
		if (eol) {
			ItemNewline *item = memnew(ItemNewline);
			item->line = current_frame->lines.size();
			_add_item(item, false);
			current_frame->lines.resize(current_frame->lines.size() + 1);
			if (item->type != ITEM_NEWLINE) {
				current_frame->lines[current_frame->lines.size() - 1].from = item;
			}
			_invalidate_current_line(current_frame);
		}
		pos = end + 1;

	queue_redraw();
