WhatsApp web overrides basic text box functionality

While typing a message, pressing Ctrl + Delete opens a "Clear this chat?" dialog instead of deleting the word to the right of the cursor.

Who on the WhatsApp team thought it was a good idea to override basic text box functionality with an option to clear the entire chat?

I’d love to meet the people who need to clear their chat more often than they need to delete a single word.

If anyone has any contact at WhatsApp, please tell them to reverse this insanity.
