📄 Description

When our text buffer is full, newlines cause the buffer to scroll underneath the viewport (rather than the viewport moving down). This was causing selections made during text output to scroll down. To solve this, when we increment the circular buffer, we decrement the y-coordinates of the current selections by 1. We also invalidate the previous selection rects.

Closes #10319
