Clear buffer doesn't clear scroll marks

[stanio]

Windows Terminal version

1.24.10921.0

Windows build number

10.0.19045.0

Other Software

• bash (inside WSL, and with Git for Windows Bash)
• cmd (Windows Command Prompt)

I'm experiencing this on two other Windows 11 machines, as well.

Steps to reproduce

• Fill in scroll marks, f.e. by repeated Enter (empty command)

• Press Ctrl+Shift+K (Clear buffer)

Expected Behavior

Scroll marks should be cleared.

Actual Behavior

Scroll marks are not cleared, and they are not updated properly further.

After Ctrl+Shift+K:

Repeat empty commands halfway though and issue cls command:

Only the marks before the current position get cleared:

Next, no new marks appear:

until I pass the "stale" marks position and issue cls again.

Same steps could be repeated with bash and its clear command.

For comparison, bash's (readline's) Ctrl+L (clear screen, keep buffer) and Ctrl+Alt+L (clear buffer) work as expected. I use the standard Command Prompt a lot so these are not always an option for me.
