Tapping caps-lock for escape not working in AlfredApp

[Nicklas Gummesson]

For some reason tapping caps-lock doesn't appear to trigger the esc when Alfred's search input is focused. Looking in the Karabiner-EventViewer app I notice that only left_control is logged:

eventType:FlagsChanged    code:0x37       name:left_command    flags:Cmd                                misc:
eventType:FlagsChanged    code:0x37       name:left_command    flags:                                   misc:
eventType:FlagsChanged    code:0x3b       name:left_control    flags:Ctrl                               misc:
eventType:FlagsChanged    code:0x3b       name:left_control    flags:                                   misc:

I also tried Spotlight which logs the same (only left_control), but at least it closes the search.

Any ideas on how to fix/troubleshoot this further?

In case something else runs into the same problem:
I noticed that it did not always happen. After some more digging it appeared to be some interference with internal keyboard shortcuts of Alfred, disabling ctrl for show actions it now appears to work as expected:
