delete_transient does not delete _transient_timeout_name

[neoxx]

Hi,

I currently reworked one of my plugins to use a transient instead of an option for caching. - Now, I also wanted to provide a clean uninstall, thus not leaving the transient in the options-table.

Obviously, the transient itself can be removed from the database by the usage of delete_transient($name), though a _transient_timeout_name remains.

Is there a particular reason for leaving this value? I know, that it is not auto-loaded, but imho still garbage...

Seems if transients expire their respective timeouts are removed. This only occurs when transients are specifically deleted.

(In [13911]) Delete _transient_timeout_$name and _site_transient_timeout_$name when specifically deleting transients. Fixes #12782
