FYI, as of alpha 37, this bug still exists.
May I also suggest a minor improvement? Currently, when holding down Shift key and then press Home key, the line starting from the cursor position back to the first column will be selected. Would it be possible that if we click Home key again (while holding down Shift), the selection is made till the first non-blank character, and if we click Home again, it is back to the first column again? This behavior would be consistent with other popular editors. Thanks.
