Still does for me in a vanilla Emacs.  Maybe it's something in your config?

That's what we do for most new features.  But sometimes the annoyance
for N users of having to disable a "feature" is eclipsed by the expected
benefit for M users getting this new "feature" without having to figure
that they want it nor how to get it.

For any change to Emacs (new feature, change to defaults, bug fix, you
name it), one can easily come up with some scenario where the change
results in an undesired result [ the credibility/likelihood of the
scenario may vary widely, of course ].  So the only really safe way to
avoid introducing new problems is to leave the code 100% unchanged.
