I guess this bug has something to do with the error log in the editor:

It seems the code failed to remove the control from menu panel. I will try to fix this bug : )

void Node3DEditor::remove_control_from_menu_panel(Control *p_control) {
	ERR_FAIL_NULL(p_control);
	ERR_FAIL_COND(p_control->get_parent() != context_toolbar_hbox);

	p_control->disconnect("visibility_changed", callable_mp(this, &Node3DEditor::_update_context_toolbar));

	context_toolbar_hbox->remove_child(context_toolbar_separators[p_control]);
	context_toolbar_hbox->remove_child(p_control);
	context_toolbar_separators.erase(p_control);

	_update_context_toolbar();
}
