Events Page error

Description of problem:
When on the events page, the events stream grid isn't accessible by screen reader (particularly tested with Voice Over). It is read as "grid 0 columns 8 rows" and the user is unable to get into the grid. This error was noticed through axe testing, the error looks as follows: 
 {
    "data": [
      "cell",
      "columnheader",
      "rowheader",
      "gridcell"
    ],
    "id": "aria-required-children",
    "impact": "critical",
    "message": "Required ARIA children role not present: cell columnheader rowheader gridcell",
    "relatedNodes": [
      {
        "html": "<div class="co-sysevent--transition" role="row" style="height: 171px; left: 0px; position: absolute; top: 279px; width: 100%;">"
      }
    ]
  }

This seems to affect the following pages: 
http://localhost:9000/k8s/ns/default/events
http://localhost:9000/k8s/ns/openshift-machine-api/events
http://localhost:9000/k8s/ns/a-serverless-example/events
http://localhost:9000/k8s/ns/knative-serving/events
http://localhost:9000/k8s/ns/knative-serving-ingress/events
http://localhost:9000/k8s/ns/kube-system/events
http://localhost:9000/k8s/ns/openshift-authentication/events
http://localhost:9000/k8s/ns/openshift-cluster-node-tuning-operator/events

How reproducible:
You can see this error by using the Axe Chrome Extension. 

Steps to Reproduce:
1. Inspect the page,
2. Click on the axe tab
3. Click "Analyze" - this issue is the one that says, "Certain ARIA roles must contain particular children"

Alternatively, you can open up VO by pressing command and F5, press control, option, and U to open the rotor, use the arrow left and right keys to get to the table menu, find the grid, then try to navigate into the grid (you can get into an item by pressing control, option, shift, and down arrow then navigate by control, option, right and left arrow).

Actual results:
An events stream grid that is inaccessible by screen reader.

Expected results:
To be able to navigate and understand the events stream grid through screen reader.
