Lots or errors in 0.9.20

When I load the plugin, I get lots of error messages in the console:

```
helpers.js:153 Uncaught TypeError: Cannot read properties of undefined (reading '1')
    at HTMLDivElement.<anonymous> (VM205 index.0f679f3d.js:1:93984)
    at HTMLDivElement.g (helpers.js:151:57)
(anonymous) @ VM205 index.0f679f3d.js:1
g @ helpers.js:151
```
