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
if (expr.size() < 1) {
				add_text("[");
				pos = brk_pos + 1;
			} else {
				String identifier = expr[0];
				expr.remove_at(0);
				Dictionary properties = parse_expressions_for_values(expr);
				Ref<RichTextEffect> effect = _get_custom_effect_by_code(identifier);
				if (!effect.is_null()) {
					push_customfx(effect, properties);
					pos = brk_end + 1;
					tag_stack.push_front(identifier);
				} else {
					add_text("["); 
					pos = brk_pos + 1;
				}
			}
		}
