NTP quick actions (Customize, Settings, etc) are not placed on NTP SI appropriately when the clock is removed from view - Follow up to 28736

[LaurenWags]

Description

Found while testing #28736.

If you remove the clock from view on NTP, when an NTP SI is displayed the actions normally in the lower right corner (Customize, Bookmarks, etc) are now displayed about halfway up the NTP.

Furthermore, if the widgets aren't displayed either, these actions are "behind" the clickable NTP SI area, so clicking on them results in you visiting the area the URL is set to.

Steps to Reproduce

1. Remove all items from view on NTP
2. Navigate to NTP SI if not already on one
3. See Customize, Settings, etc about halfway up the page
4. Try to click on Customize to fix clock view, get directed to clickable area's URL
5. If you go to regular NTP, Customize, etc display appropriately
6. Re-enable cards/widgets only (not clock)
7. Nav to NTP SI again
8. Customize, etc are still improperly placed.

Actual result:

Nothing on NTP SI	Cards/Widgets only	Clock only	Regular NTP

Expected result:

Customize, etc should always be placed appropriately on NTP SI even if elements like clock are not displayed

This is from 1.49.120:
