Exposed views date filter with offset not working as expected

I finally created this https://www.drupal.org/project/date_filter → to address this issue and many other.
Looks like issues like this have a very small chance to get enough attention and find their way into core so we have to handle that in contrib :(

Building on #44. Adding similar improvement as #38 but to the datetime filter in core datetime module.

Try fixing CCF.

Was previously tagged for tests and issue summary update which still need to happen plese.

Also please include interdiffs with patches.

Exactly same as #47, just re-rolled for 10.1.x

Hello,

I tried to apply patch on comment #50, but it's thrown an error in datetime module :

Warning: Undefined array key "type" in Drupal\datetime\Plugin\views\filter\Date->getOffset() (line 180 of core/modules/datetime/src/Plugin/views/filter/Date.php).

Without this warning, the patch works perfectly on Drupal 10.2.2!
