Twitter cache remains after I delete private data

[CantankRus]

I haven't used twitter before but signed up just to have a look.
Why does a twitter Cache Storage remain in chrome://settings/siteData when I delete everything besides passwords?
Used both the vivaldi and chrome dialogs (chrome://settings/clearBrowserData) to delete but a 3.7mb cache remained even after restarting vivaldi.

Edit:
After manually deleting the twitter Cache Storage, it is not recreated when I log in to twitter and all private data is deleted as expected.
However, I tested again by creating another twitter account and it appears this cache is created
when you confirm your email address and again can only be deleted from the chrome dialog.
Seems very odd to me why this twitter Cache Storage would persist???

@CantankRus
You shouldn't use chrome://settings/clearBrowserData, I remember had issues some snapshots ago.

You can try to place [*.]twitter.com with block or clear on exit at chrome://settings/content/cookies as default cleaning options don't cover local storage at all (yet)

I see the same for https://www.theatlantic.com where the Vivaldi Cache Storage doesn't delete using the
clear private data dialog or if I enable the setting "Keep local data only until you quit your browser".
Works in google-chrome.

Are you saying cache clearing isn't fully implemented yet and I would need to check occasionally and manually delete?

Yeah, the local storage has to be deleted manually for each site – I hope they let us clean it through the "clear private data" option at some point. Currently I don't know if any extension exists that can do this.

Until chromium or vivaldi implement improve this. Soon, I hope.
(Clearing such data actually improve overall performance)
Few extensions exist.

@hadden89 Have you actually tried clearing local storage with any of these? Because it doesn't seem to work.

[Hadden89]

@luetage Nope, but they are managers, so I think they don't work that way.
The cookie API should cover also local storage and service workers. But it doesn't work yet.
