Expected / Desired Behavior / Question

After upgrading to v3.18.1 I'm getting this error when trying to use the FileTypeIcon component.

TypeError: Cannot add property onClick, object is not extensible
    at FileTypeIcon.render 

Observed Behavior

I expected it to render the file icons based on the given path, but it crashes the page.

Steps to Reproduce

Using SPFX 1.19.0, import and use the FileTypIcon component:

  <FileTypeIcon type={IconType.image} path={file.Filename} />

This seems to be related to the additional props that were added to this component in v3.18.0? Pull Request

Thanks!

I rolled back to SPFX 1.18.2 and it also has the same error and crashes the page.
