Unsubscribe doesn't work as expected

[ewoks]

Describe the Bug

Although I unsubscribe, sometimes channel comes back to my subscription list

Steps to Reproduce the Bug

• Add subscription
• Go to home to check if subs section is populated
• Add another subscription
• Check again
• Go to manage subscription and click on the "x" to delete initial subscription
• Popup with red text states "Unsubscribed from ABC" and stay floating in the upper right corner
• Going to home and subsription section doesn't show videos from removed channel anymore (popup still floats there)
• Dismiss the popup (while on home page)
• Refresh the home page and videos from unsubscribed channel re-appear in subs section
• Click on Subscription section text -> Manage (to check list of all subscriptions)
• Old subscription is still in the list on the "Manage subscriptions" screen

Expected Behaviour

Once user unsubscribes from specific channel and dismiss the popup (which offers optional undo of the unsubscribe action), the subscriptions list shouldn't contain removed channel anymore.

Device Info

• Device: PC
• OS: irrelevant
• Browser: Chrome
• Version: 124.0.6367.118

Additional Context

This might be a problem of undo functionality. If popup is not dismissed I couldn't reproduce the bug, so I have a feeling that dismissing popup (by clicking on it's "x") actually triggers undo of removed subscription.
