ConfigMaps Data editor crashes with: Uncaught TypeError: t.match is not a function

[zerouid]

When I open a config map the data editor initially loads the the raw data strings (escaped JavaScript string), but immediately after this the content disappears and the exception below is logged to the console. After the crash the UI becomes unresponsive and I have to reload the page.

Environment

Installation method: https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta3/aio/deploy/recommended.yaml
Kubernetes version: v1.14.3
Dashboard version: v2.0.0-beta3
Operating system: linux/amd64
Node.js version ('node --version' output):
Go version ('go version' output):
Web browser: Google Chrome  v76.0.3809.132 / macOS

Steps to reproduce

1. Open Kubernetes dashboard and log in using Kubeconfig or Token.
2. Go to any existing ConfigMap that contains data.

Observed result

The raw data string appears in the editor and quickly disappears and the UI remains unresponsive. In the Developer console the following error appears:

Uncaught TypeError: t.match is not a function

    at main.a265afe24a905d94a59f.js:1
    at Us (main.a265afe24a905d94a59f.js:1)

Expected result

To be able to view and edit ConfigMap data.
