This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgment at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

If I create a ".dir-locals.el" that applies to all major modes, such as:
  ((nil . ((tab-width . 3))))
It works when first opening any file under that directory- good. But, if
I switch the buffer's major-mode, it loses the directory-local
tab-width - and I've seen it lose other variables as well.

An alternate case showing the same is to have a ".dir-locals.el" like:
  ((js-mode . ((tab-width . 3))))

and opening a non-JS file in the directory, such as an HTML file, and
then switching to js-mode. Since I'm now editing the file in js-mode,
I would want it to read the js-mode dir-local variables.

Losing dir-locals seems like a bug to me, though perhaps there is a
reason for it. I did notice from other dir-local-related bugs that
they require some
thought as to how to handle edge cases...
