Ctrl+S not working properly

[bantya]

Current Behavior

The keyboard combo Ctrl+S does not work consistently for all use cases. For creating a snippet, it works randomly and not guaranteed to work next time. For saving an edited snippet, it simply does not work.

Expected Behavior

The aforementioned key-combo should work the same for both the cases:

1. While creating a brand new snippet and,
2. While editing an existing snippet.
