I assumed that "default mode" means "not posix mode", but if so that
doesn't hold up:
$ mkdir tmp/a
$ cat >tmp/a/b
echo in B
$ ( PATH=$PWD/tmp/a source b )
in B
$ ( PATH=$PWD/tmp source a/b )
bash-latest: a/b: No such file or directory
$ echo $BASH_VERSION
5.3.0(2)-alpha
$ ( p=$( realpath "$0" ) ; echo "git commit ${p##*/bash/}" )
git commit aadb6ffb93359891760c58008539f549f06c5140/bin/bash
$ shopt -o posix
posix off
