PR Description:

Changes Made:
In this PR, we've made a modification to the hide_notification function in the notification.js file. The change ensures that the notification is not hidden if notifications_muted is set to true. This adjustment is intended to align the behavior of the notification system with the requirement that when notifications are muted, the notification should not be hidden.

Reason for the Change:
Previously, the hide_notification function would always hide the notification after a certain period, regardless of whether notifications were muted or not. This behavior needed to be updated to accommodate the case where notifications are muted and should remain visible.

Impact of the Change:

• When notifications_muted is true, the notification will not be hidden.
• When notifications_muted is false, the notification will be hidden after the specified duration (5 seconds in this case) as before.

This change ensures that the notification system behaves as expected when notifications are muted.

I've made a change that prevented your code from working correctly, this also solved another issue I was having. Thanks for your work on this!
