Until the last version, 3.4.15, you could press Control + Enter in the Commit Message box to apply the commit.

As of version 3.4.16 this no longer works.

Steps to reproduce:

Stage a file

Go to Commit (Control + 1)

Type a commit message in the Commit Message box at the bottom

Press Control + Enter

Expected behavior:

The change is committed as if I clicked the Commit button.

Observed behavior:

Nothing happens
