wp-editor-area too narrow in Text Edit mode

i’m pretty sure you used to be able to set the rows and columns for the editor. can you not just drag the bottom right hand corner down and across so it’s the size you want while you’re editing?

There’s nothing to drag; the 40-col boundary has no handles or markers.

There’s a mu-plugin filter to fix this problem:

I changed it to 80 cols and kept the height the same, since the box height drag works.

I wonder if WP has this issue in the bug list?
