Issue:
Typing Text Effect not typing sequentially when using an effect tag
**Describe the bug**
Typing text effect _using tags_ will type each line immediately rather than sequentially

**To Reproduce**
Create a UIText Box with a lot of text, a multi-line section of it surrounded by the `<effect id=typing> ..... </effect> `and later activate the typing text affect with `.set_active_effect(TEXT_EFFECT_TYPING_APPEAR, effect_tag="typing")`

**Expected behaviour**
There are two ways to create the typing text effect, one on the entire element, and one on a tagged section within the UITextBox. The entire element way treats multi-line text correctly, tying out the first line of text, then the following line, etc. The tagged chunk method treats multi-line text incorrectly, typing out each line immediately.  As per the discussion in Discord, this is not the intended behavior
