Searching among messages within 'All Accounts' also shows messages unrelated to the query
When executing a freetext search for messages within the 'All Accounts' section, the search results include messages that are unrelated to the query. Although these unrelated messages appear to match the search criteria based on their displayed sender and/or subject, selecting the email reveals a different sender and/or subject.
The screenshots below show what I mean: the first one has the first message found by the search marked; the second one, the penultimate message marked (both the penultimate and the last one are from the same sender).
