I can confirm this for both 5.2.21 and the development branch. The backticks
are not quoted as they ought to be, resulting in a command substitution.

I was not able to reproduce this, however.
$ cd ta<TAB><TAB><TAB><TAB>
$ echo "${PWD@Q}"
$'/home/kerin/tange/tab/\n`/tmp/trip`>'
$ cd ../../../..
$ cd ta<TAB><TAB><TAB><TAB><TAB>
$ echo "${PWD@Q}"
$'/home/kerin/tange/tab/\n`/tmp/trip`>/tmp'
That was with programmable completion disabled (shopt -u progcomp) and the
following directory structure in place.
$ LC_ALL=C find . -mindepth 1 -exec ls -1d --quoting-style=c {} +
"./tab"
"./tab/\n`"
"./tab/\n`/tmp"
"./tab/\n`/tmp/trip`>"
"./tab/\n`/tmp/trip`>/tmp"
"./tab/\n`/tmp/trip`>/tmp/tripwire;\n'@<?[]|~\\"
"./tab/\n`/tmp/trip`>/tmp/tripwire;\n'@<?[]|~\\/tmp"
