Ctrl + SHIFT + D conflicts with browser shortcuts

[quantum_leap]

Ctrl + SHIFT + D, the shortcut for duplicating blocks doesn't work as expected.

Let's take Chrome, for example.

Case where it works

1. Create a block
2. Execute the shortcut inside the editor
3. Shortcut works

Case where it doesn't work

1. Create a block
2. Select the block in the List View, then click it one more time
3. A blue border appear around the block in the block editor
4. Execute the shortcut
5. The "Bookmark all tabs" Chrome modal appears

At this point, if you click another block, shortcut works. There seem to be an issue when a block is clicked twice from the List View. That's where browser takes over and the shortcut doesn't work.

Same thing with Firefox but for this browser, the "Add bookmark" modal opens up.

That's generally quite annoying and it has been there forever.
