React error when using `maxWidth`

[christianTNG]

When using the maxWidth I can correctly format my email but during each rendering I get a React error in the console that maxWidth was passed to appear in the DOM but is not recognized. Here is the full error:

  React does not recognize the `maxWidth` prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase `maxwidth` instead. If you accidentally passed it from a parent component, remove it from the DOM element.

Could you please make sure that the additional props like maxWidth are not propagated to appear in the DOM or changed to lowercase before? Thank you very much in advance!
