ctrl+backspace on the first word of a line sends cursor to previous line

I depend on shortcuts like ctrl+backspace, to the point where every time i use msword i have to disable "adjust paragraph spacing automatically" because it changes the ctrl+backspace behaviour and that screws with my muscle memory.

In most implementations, ctrl+backspace on the first word of a line will delete that word and move the cursor to the start of that line.
However, this implementation moves the cursor up to the previous line instead of the start of the current line.
Automatic disqualification til ya fix this.
