using {virtual_mode: "vertical"} and "none" causes containing web page to fail to load

## Bug Report

### Steps to Reproduce:

I'm trying out the new `virtual_mode` option for `setDataListener`:

https://github.com/jpmorganchase/regular-table/blob/6dbee4ffe1b3c1342ae3903a39456aa9d5131cda/src/js/index.js#L272-L279

The `both` and `horizontal` options seem to work fine, but trying to use either `vertical` or `none` causes the webpage containing the `` to fail to load.

### Expected Result:

`vertical` and `none` functioning as described in #125

### Actual Result:


Before that error pops up, the page will try to load for about 30 sec (while displaying only a white screen, with no loaded sources visible in devtools).

### Environment:

`regular-table@0.3.0`

### Additional Context:

This bug is happening in a regular table included in my `` element
