See title. They worked fine in some previous version of SB.
I suspect SB somehow got " to be bound to something else. In vim, one would type "ayy to yank the current line (yy) into register a ("a). But now, typing " in NORMAL mode as usual simply inserts a double quote instead.
Nothing has changed with codemirror-vim (named registers are still supported).
Using 2.4.1-3ddfab51e828a1b105264cb7f51101b461419d4f-2026-02-13T19-05-36Z if that matters.
