... and actually, it seems to happen not only for new dired buffers but
also when:

1. C-x b'ing back to a dired buffer
2. Just clicking or C-o'ing into the dired buffer (in split window mode)
3. Leaving the mini-buffer while the dired buffer is active (either by
completing the command, or by C-g'ing it)

Also, when dired has the focus and the frame is currently narrower or
equal than what dired wants, set-frame-width with a width smaller than
95 is ineffective.

When dired does have the focus, and the frame is currently wider or
equal than what dired wants, set-frame-width with a width smaller than
95 performs as if 95 had been given.
