Copying wrapped lines includes a newline character

[lindhe]

Windows Terminal version

1.21.3231.0

Windows build number

10.0.22631.0

Other Software

Ubuntu 24.04.1 LTS (WSL2)

Steps to reproduce

1. Type a long string, until it wraps at the window width:

   $ aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

2. Select the text to copy it.

3. Paste it, observe the newline introduced at the point of wrapping.

Expected Behavior

Copy the literal string, not the newline.

Actual Behavior

It copies a newline at the point of wrapping. In my example with my particular font and window size, it becomes:

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaa

Can you try this again with Preview 1.22/? https://aka.ms/terminal-preview

Seems to be working as intended in Preview.

Considering this has been a recurring issue, would you consider adding some tests to catch it the next time it happens?
