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
main = memnew(ItemFrame);
	main->index = 0;
	current = main;
	main->lines.resize(1);
	main->lines[0].from = main;
	main->first_invalid_line.store(0);
	main->first_resized_line.store(0);
	main->first_invalid_font_line.store(0);
	current_frame = main;
	vscroll = memnew(VScrollBar);
	add_child(vscroll, false, INTERNAL_MODE_FRONT);
	vscroll->set_drag_node(String(".."));
	vscroll->set_step(1);
	vscroll->set_anchor_and_offset(SIDE_TOP, ANCHOR_BEGIN, 0);
	vscroll->set_anchor_and_offset(SIDE_BOTTOM, ANCHOR_END, 0);
	vscroll->set_anchor_and_offset(SIDE_RIGHT, ANCHOR_END, 0);
	vscroll->connect("value_changed", callable_mp(this, &RichTextLabel::_scroll_changed));
	vscroll->set_step(1);
	vscroll->hide();
	set_text(p_text);
	updating.store(false);
	validating.store(false);
	stop_thread.store(false);
	set_clip_contents(true);
}
RichTextLabel::~RichTextLabel() {
	_stop_thread();
	memdelete(main);
