Write On Start option not working

[arvz]

Describe the bug
When disabling Write On Start on TMPWriter, the writer still automatically starts writing when on Start()

To Reproduce

1. Create a gameobject with TextMeshProUGUI component and TMPWriter component
2. Set some text in the TextMeshProUGUI
3. Disable Write On Start option on TMPWriter
4. Start game, observe the writer begins writing

Expected behavior
TMPWriter shouldn't begin Writing automatically

I've put a debug log in the StartWriter() method, and the stack trace is:

You also have to disable "WriteOnNewText", since the first text is also considered a new text.
Which is because TextMeshPro invokes the TEXT_CHANGED_EVENT once for every TMP_Text when first enabled.

Let me know if that solved your issue or if something else is going on ✌️
