Broken Alt+Shift keyboard layout switcher interaction with Alt menu key

Bug Reports
#1

Description

This seems to be a bug with Electron apps in KDE in general. When the menu bar is enabled (either shown or auto-hiding), every time I switch the keyboard layout with Alt+Shift, the menu steals focus from the input control.

To Reproduce…

Steps to reproduce the behavior:

  1. Install KDE.
  2. Have at least two keyboard layouts.
  3. Set the keyboard layout switch to Alt+Shift.
  4. Open Mailspring.
  5. Press Alt+Shift to switch keyboard layouts.

Expected Behavior

The keyboard layout is switched and the menu doesn’t get focus.

Setup

  • OS and Version: Kubuntu 21.10 (KDE)
    • Installation Method: snap
  • Mailspring Version: 1.9.2

Additional Context

I’ve worked around by switching to the hamburger menu, which disables the menu bar entirely.

This bug should be fixed in Electron 13.1.0 and above: https://github.com/electron/electron/releases/tag/v13.1.0
