Maybe this can be added as an additional bug/fix … As I found, elm-apps crash when screen-readers are used:

the same topic was also discussed here:

> [@Elm app not compatible with ChromeVox screen reader](https://discourse.elm-lang.org/t/elm-app-not-compatible-with-chromevox-screen-reader/3682):

> When I try to run my Elm app with [ChromeVox](https://chrome.google.com/webstore/detail/chromevox/kgejglhpjiefppelpmljglcjbhoiplfn?hl=en), I see a continual stream of “Uncaught TypeError: Cannot read property ‘childNodes’ of undefined”. What I’m guessing is I’m hitting a case similar to [what is described here](https://discourse.elm-lang.org/t/fullscreen-elm-app-in-0-19-childnode-issue-reopened/3174): i.e. it’s caused by Elm taking over the body. Do I have any resolution to make my app compatible with screen readers?

Additionally, the same error occurs, when googletranslate is used. All systems change the dom slightly, however this patch seems to work and solves the problem …
