Comment (by Mte90):

 Thanks now is more clear, so the guilty transient is `_transient_feed_`
 that include the whole feed.

 This is the file that save the feed in a transient
 https://github.com/WordPress/wordpress-
 develop/blob/2382765afa36e10bf3c74420024ad4e85763a47c/src/wp-includes
 /class-wp-feed-cache-transient.php and this one that fire the saving in
 the cache https://github.com/WordPress/wordpress-
 develop/blob/32151af6e47e0fda4c7ac1796eb8ac8916817517/src/wp-
 includes/feed.php#L805

 Thinking of this, I am wondering if we clean all the transient generated
 by the feed support from the content is a good thing. As other people can
 use it also for other things, so a way should be ignoring content just for
 specific feeds.

 As this can impact:

 * RSS block: https://github.com/WordPress/wordpress-
 develop/blob/2382765afa36e10bf3c74420024ad4e85763a47c/src/wp-
 includes/blocks/rss.php#L16
 * RSS widget: https://github.com/WordPress/wordpress-
 develop/blob/c622c4baddebb621bf3b496d2c8b6de4779f00c8/src/wp-
 includes/widgets/class-wp-widget-rss.php#L66
 * RSS widget functions: https://github.com/WordPress/wordpress-
 develop/blob/00bc227eb8e7b09e9eb6390a74a23a3f3fcc2383/src/wp-
 includes/widgets.php#L1527
 * Dashboard widget: https://github.com/WordPress/wordpress-
 develop/blob/9d3e32ecbf1a8c8964a8b51b225ec3c1ba2f53f1/src/wp-
 admin/includes/dashboard.php#L1242

 Looking at these only the block use the excerpt from the feed RSS so in
 that one is needed to keep that content but in the other ones is not
 required.
