Rows should remember their width (MeasureRight())

[0x152a]

Windows Terminal version

1.21.2361.0

Windows build number

10.0.22631.0

Other Software

• System Language: zh_cn
• Console Font: Hack Nerd Font Mono
• Font Size: 12

Steps to reproduce

1. Print more than two lines ending with space and causing line wrap

# `120` here is my console width
for i in range(2):
    print('x' * 120 + ' ')
print('yya')
input('--')

2. Resize the window to change the console width.

Expected Behavior

Cursor should be after -- of input('--') throughout the process

Actual Behavior

After resize, cursor is before a of print('yya')

• Before resize: (width is 120)
  
• After resize: (width is 121, line wrap here seems wrong too)

Thanks for filing! We recently rewrote ConPty. Mind checking v1.22 (Preview) to see if it got fixed /?

Also, thanks @ayush1233!

Thank you for the update. I've tested version 1.22.240823002-preview and found that the cursor position issue has been resolved.

However, I've noticed that the line wrapping still seems to be incorrect. That is, the spaces at the end of lines seem to be ignored after adjusting the window width. (Maybe I should open another issue?)

That is, the spaces at the end of lines seem to be ignored after adjusting the window width.

That's a known issue that we're hoping to address at some point. I'm not entirely sure if we have an issue to track it though. We could repurpose this one for it.

The reason that happens is because our text buffer does not keep track of how much text you wrote on any given line. To it, there's no difference between whitespace and no text at all, and so it gets truncated during resize.
