Ctrl+Enter doesn't work in git commit window

Normally, in git commit window, Ctrl+Enter hotkey combination results in confirming commit. This hotkey combination doesn't work in QtCreator 14 version https://code.qt.io/cgit/qt-creator/qt-creator.git/log/?id=1b4f1e5bd748ad8a23f7a3e7479d64a7e95f2bd5.

Steps to reproduce:

1. Make changes to a file in git repository.
2. Invoke git commit or git amend (Alt+G, Alt+C or Alt+G, Alt+M)
3. Select the modified file(s) on the right and type a commit message.
4. Press Ctrl+Enter.

Expected result: Commit is performed/amended, git GUI closes.

Actual result: Nothing happens. The Commit button on the bottom right is active, and I can click it with mouse to perform the commit.
