Relations disappear after merging their target/source

[s2fische]

While curating in annotation mode, we found that some relations "vanish" after their target or source points are manually merged (in this case, the one named "Element von"), see video. We expect the relation to continue being displayed/stay selectable after the corresponding target or source are merged.

We're not sure whether the issue is due to the stacked spans/entities because in this case, the entities have different names.
