after-skip of tables adds up with the before-skip of the following environment

[mhottenroth-le-tex]

As the title states, the current behaviour of tables is that their after-skip will add up with the before-skip of any environment that follows them, despite using \addvspace{…} or \minusvspace{…} in the follow-up environment. This is only true for tables, not for figures; figures show the expected behaviour, i.e. merging the vertical spaces according to the rules of \addvspace{…} or \minusvspace{…}, respectively.

An MWE for testing:
