We won't be able to clear the one failed build, so I'm going to admin merge this when it's time. |

I think you can do it for the lastCharacterViewport parameter too.
Then the call you have in screenInfo doesn't have two std::nullopts passed through.
Up to you tho

Summary of the Pull Request
Currently, when the user resizes the Terminal, we'll snap the visible viewport back to the bottom of the buffer. This PR changes the visible viewport of the Terminal to instead remain in the same relative location it was before the resize.

Detailed Description of the Pull Request / Additional comments
We already hated the
std::optional<short>&thing I yeet'd into #4741 right at the end to replace ashort*. So I was already going to change that to astd::optional<std::reference_wrapper<short>>, which is more idomatic. But then I was looking through the list of bugs and #3494 caught my eye. I realized it would be trivial to not only track the top of themutableViewportduring a resize, but we could use the same code path to track the visible viewport's start as well.So basically I'm re-using that bit of code in
Reflowto calculate the visible viewport's position too.Validation Steps Performed
Gotta love just resizing things all day, errday
