In the [Flyout documentation](https://elastic.github.io/eui/#/layout/flyout), I get the following error when clicking on the Properties for the first flyout demo:

`TypeError: Cannot read property 'split' of undefined at markup (https://elastic.github.io/eui/bundle.js:343920:15) at https://elastic.github.io/eui/bundle.js:344052:33 at Array.map (<anonymous>) at GuideSection.renderPropsForComponent (https://elastic.github.io/eui/bundle.js:344029:28) at https://elastic.github.io/eui/bundle.js:344214:23 at Array.map (<anonymous>) at GuideSection.renderProps (https://elastic.github.io/eui/bundle.js:344213:34) at GuideSection.renderContent (https://elastic.github.io/eui/bundle.js:344272:86) at GuideSection.render (https://elastic.github.io/eui/bundle.js:344286:23) at finishClassComponent (https://elastic.github.io/eui/bundle.js:203439:31)`

What browser are you on? I was able to open the flyout on Chrome and Firefox.

Looks like that error is happening here: [https://github.com/elastic/eui/blob/master/src-docs/src/components/guide\_section/guide\_section.js#L23](https://github.com/elastic/eui/blob/master/src-docs/src/components/guide_section/guide_section.js#L23)

I am not seeing anything immediately obvious as to the issue. Is there anything specific about your environment that would help us reproduce?

Chrome v72.0.3626.121 on Windows 7.

But I also get an error on Chrome and Safari on iOS 12.1.4:

I’ve tried several Props table links in other Eui docs and they all open without error.

I’m a tech editor by trade and not a developer, so I don’t really know how to decipher this.
