State: closed
Merged: No

That's a weird one I found while working on #17445...
The _viewport in conhost is basically the section of the buffer that
gets render on the screen. The _viewport.Left() is effectively the
horizontal scrolling position. I don't think we should use that for
the VT viewport. This PR changes it so that the VT viewport always
spans the full width of the buffer. This makes it possible to address
the full width of the buffer with CUP sequences.

Part of #14000
