[BUG] TextField crashes with a certain input

This pertains to OpenFL 8.9.6. With a certain input, TextField crashes at TextField.hx::__updateScrollV. The crash occurs in the following code:

var i = lineIndex, tempHeight = 0.0;

		while (i >= 0)
			if (tempHeight + __textEngine.lineHeights[i] <= height - 4)
				tempHeight += __textEngine.lineHeights[i];

because “i” goes out of boundaries of the __textEngine.lineHeights array. In order to reproduce the crash, create a TextField of type INPUT and enter 2 spaces. At this point the crash should occur.

I have both scrollVs completely fixed on a branch, so I may just PR or merge those since they are causing issues…
