Description (last modified by SergeyBiryukov)

Just faced this issue - for some reason, the transient was not deleting itself. While checking the DB, the option with the transient was there, while the timeout option was missing (probably a glitch while saving to DB).
Now, if you check get_transient() in option.php (quick link https://core.trac.wordpress.org/browser/tags/4.9.8/src/wp-includes/option.php#L0 ) you can see that these are deleted only if both exist and both pass the test:

[...]
 if ( false !== $timeout && $timeout < time() ) { DELETING TRANSIENT}
[...]

Otherwise transient will hang... forever. This should be tuned up so it also checks that these options exist, and delete transient if timeout is absolete.
