iterm2 triggers "double ⌘C" shortcut of Deepl when hitting ⌘C once

Deepl application listens on double ⌘C shortcut. That means if user presses ⌘C twice quickly, Deepl window opens and translates the selected text. This works great for all applications, except iterm2! iterm2 is the only application where deepl window triggers after each, single ⌘C.

• iTerm2 version: 3.3.9
• OS version: 11.2.3
• com.googlecode.iterm2.plist
• debuglog.txt
• screenrecording.gif

Detailed steps to reproduce the problem:

1. Install https://www.deepl.com/en/app/
2. Hit ⌘C in iterm2 window

Also check out screenrecording.

What happened: Deepl window opened

What should have happened: Deepl window shouldn't have opened. It's configured to open only on double ⌘C
