Package: Emacs
Version: 30.0.50


Many packages use the `major-mode` as a proxy for the type of content
in the buffer.  When using the new TS modes, these packages tend to
behave poorly because they do not understand that a buffer in `js-ts-mode`
contains Javascript.

I suggest we add the non-TS mode as an extra parent, so
`derived-mode-all-parents` includes `js-mode` in `js-ts-mode`.
