For example recording fae5636e-1d6c-4162-ac9e-40de9901396e on
https://musicbrainz.org/report/DeprecatedRelationshipRecordings?page=25 has a pending edit yet is not highlighted in the report.

Unsurprisingly they are also not highlighted elsewhere:

On the other hand when there are merges they are highlighted:

Without any visual cues or way to filter which recordings are already being edited working on these reports can be rather uncoordinated unless one recognizes the recordings.
Visited link highlighting is insufficient as often many recordings from a release are edited at once.
