Topic on Talk:Page Previews/Flow

When an article links to a specific section of an article, rather than the general article, should we display the lead sentence (and possibly even photo) of that specific section:

Example: the Hovercard for the link [:en:Year#Besselian_year Year#Besselian year] in the [:en:Universal_Time Universal Time] article displays:

A year is the orbital period of the Earth moving in its orbit around the Sun. For an observer on the Earth, this corresponds to the period it takes the Sun to complete one course throughout the zodiac along the ecliptic."

This is confusing at best, misleading at worst. The Hovercard should read:

The Besselian year is a tropical year that starts when the (fictitious) mean Sun reaches an ecliptic longitude of 280°.

There's another more recent topic discussing this issue at https://www.mediawiki.org/wiki/Topic:Tjlsihy1b6n6nwxd, called "Hovercards don't show the section of a page that the link specifies". I have also added links to other topics discussing the same problem there.
