Hi team,
It seems that any app using a UI component from this library that extends the "withStyles()" helper function breaks in STBs using a Chrome 39 implementation in the field. The particular STB runs ES5.
Here are screenshots of the issue:



You can find an example app to replicate the issue here:

Please note that the issue cannot be replicated in modern browser.
If you need more information about which STB breaks, please contact me through internal channels.
