Description of problem:

The Watchdog 'Alert Details' page is replaced by a page stating 'No Alert Found' after a few seconds. After a few seconds more, the *Alert Details* page returns. This cycles a few times until eventually the *Alert Details* page remains visible.

Version-Release number of selected component (if applicable):

OpenShift Container Platform 4.6.0-0.nightly.

How reproducible:

Every time.

Steps to Reproduce:

1. In the Administrator perspective, navigate to *Monitoring* -> *Alerting* -> *Alerts* on a newly installed cluster.

2. Select the *Watchdog* alert name. This takes you to the *Alert Details* page for the Watchdog alert.

3. Wait for something like 20 or 30 seconds.

4. The *Alert Details* page is replaced by a page stating 'No Alerts Found'.

5. Wait a further 20 or 30 seconds and the *Alert Details* page comes back again.

6. This happens a few times and eventually the *Alert Details* page stays visible.

Actual results:

The *Alert Details* page for the Watchdog alert is temporarily replaced by a 'No Alerts Found' screen, then the *Alert Detals* page returns. This cycles around a few times before the *Alert Details* page eventually remains visible.

Expected results:

For the *Alerts Details* page to remain visible from when you first view it, without it being replaced by a 'No Alerts Found page', since the Watchdog alert is always firing.

Additional info:

I am seeing this on Firefox version 79 on Fedora 32.
