Environment

Windows build number: 10.0.19041.0
Windows Terminal version (if applicable): 1.1.2021.0

Any other software?
Ubuntu 20.04 LTS (WSL2)
WinCompose v0.9.4 (https://github.com/samhocevar/wincompose/releases/tag/v0.9.4)

Steps to reproduce

  1. Start WinCompose and Windows Terminal (cmd, powershell, or WSL does not matter)
  2. Input any character using the WinCompose compose key
    e.g. rightAlt + o a

Expected behavior

The correct character ('å' in the above example) is sent to the terminal.

Actual behavior

Seemingly no character is sent, at least nothing is displayed.

Probably related to #6309 as setting "experimental.input.forceVT": true gives the expected behavior.
