Transaction with ID { } waited on section displays unrelated contention row

**Describe the problem**

`Transaction with ID { } waited on` section displays unrelated contention row.

In the example where this issue was encountered, there are 2 transactions that experienced `High Contention`:
`e15ae857-0f76-446d-97a8-8b8f6ac019a5` and `942cc9bb-99a4-4ef3-9533-7ffe0ce1bee8`

When I click on Transaction Execution ID `e15ae857-0f76-446d-97a8-8b8f6ac019a5`, the one correct blocking statement is displayed in the `Transaction with ID { } waited on` section:


When I click on Transaction Execution ID `942cc9bb-99a4-4ef3-9533-7ffe0ce1bee86`, there are 2 blocking statements displayed in the `Transaction with ID { } waited on` section. The first blocking statement is the correct blocking statement. The second blocking statement displayed is not correct; it is the blocking statement from Transaction Execution ID `e15ae857-0f76-446d-97a8-8b8f6ac019a5`:

**To Reproduce**
I will add simpler repro steps later

**Expected behavior**
Only the related blocking statement is displayed.

**Environment:**
- CockroachDB version 23.1.2
- Server OS: Mac arm
- Client app `cockroach sql`
