Since Stackedit v5 I can no longer use shift-delete in order to cut portions of text.
Worse, it will just delete the text without copying it to clipboard so it is not available in next paste operation.

Happens in windows, linux, firefox, chrome.

Steps

• go to stackedit.io/app
• select some text
• press shift-delete
• press ctrl-v

Expected
Cut/paste operation

Happens
Delete operation
