How to stop the multiline input from jumping around

How can I stop a multiline input from jumping around when I click into it? Currently if I click into the lower 1/2 of the input field, it scrolls up automatically.

1) This is annoying beyond all
2) It's causing errors

Error:

Trying to add Code Editor Input Caret (TMPro.TMP_SelectionCaret) for graphic rebuild

while we are already inside a graphic rebuild loop. This is not supported.

Specifically it's the code on lines 2131-2143. It makes no sense to me why its even in there. The function is marked private too so I can't even remove it in a subclass.
