[Bug]: Cmd + plus does not zoom in on macOS on non-US layouts #30060

Before submitting

• I searched existing issues and did not find an open duplicate.
• I included enough detail to investigate the problem.

Area

MacOS, Desktop

Steps to reproduce

1. On macOS with an Austrian keyboard layout, open T3 Code.
2. Press Cmd + - and observe the UI shrink.
3. Press Cmd + + to increase the UI size again.

Expected behavior

Cmd + + zooms in and makes the UI larger, reversing the effect of Cmd + -.

Actual behavior

Cmd + - makes the UI smaller, but Cmd + + does not zoom in.

Impact

Minor bug or occasional failure: keyboard zoom out works, but the corresponding zoom-in shortcut does not.

Version or commit

T3 Code (Beta) 0.1.6 is installed and running on the machine.

Environment

• macOS 27.0 (build 26A428), Apple Silicon (arm64)
• Selected keyboard layout: German
• Installed and running desktop app: T3 Code (Beta) 0.1.6

Related issue

#14833 reported a similar Cmd + + failure on macOS with a German keyboard layout, while Cmd + - worked. It was closed as fixed by #18439; a maintainer requested a new issue if the problem persists. The underlying cause and whether the tested client contains that fix have not been verified.

Workaround

Menu-based zoom (View > Zoom In). Inconvenient.
