<h1 dir="auto">Steps to reproduce</h1>
<p dir="auto">vim Terminal\src\cascadia\TerminalApp\TerminalPage.cpp<br>
yank and paste second line.</p>

<h1 dir="auto">Expected behavior</h1>
<p dir="auto">pasted line appears text, below scrolls down</p>

<h1 dir="auto">Actual behavior</h1>
<p dir="auto">pasted line appears text scrolls up.<br>
At this point there is no consistency between cursor and location in the file.<br>
Hitting "u" to undo even when at the "Already at the oldest change" point removes the text under the cursor and scrolls everything up. leading  to multiple copies of the vim status line</p>
<p dir="auto">Confirms this is a problem even when ssh [-ing] to a remote machine and using vim there not the local windows instance as well.</p>
