Clicking on "Manage all notifications settings" link from the notifications modal does not anchor correctly to 'Custom Filters' LiveData

Steps to reproduce

1. Have an user with at least 10 custom notifications filters in order to populate the Custom Filters LD table
2. On a page, click on the watch settings button (next to the 'Edit' button)
3. Click on the 'Manage all notifications settings' link
4. Observe the anchor on the Notifications Preferences page

Expected results

On Notifications Preferences page, the anchor is set to Custom Filters LD table which is displayed on the top of the page (like for ex. navigating to http://localhost:8080/bin/view/Sandbox/#HStyles).

Actual results

When the user lands on Notifications Preferences page, the actual anchor is set somewhere above the Applications section, although the 'Manage all notifications settings' link points to http://localhost:8080/bin/view/XWiki/U1?category=notifications#Hnotifications.settings.filters.preferences.custom.title, which is related to Custom Filters LD table.
