Bash Version: 5.2 Patch Level: 32 Release Status: releaseDescription: A literal '~' or other tilde-prefix at the beginning of an element of $PATH is expanded when a command is executed from the bash prompt.

Yes, bash has always done this, from its earliest days. It's not a great idea, it was never documented, it's deprecated, and its use is not encouraged.
This expansion doesn't happen when bash is invoked as "/bin/sh"
(which is a symlink to bash on some systems).
POSIX clearly disallows it, so it's not enabled in posix mode (it predates
posix mode by years). By the time posix mode came along, backwards
compatibility was already an issue.
