Chatwidget has a huge invisible body that hijacks clicks

The Trengo Online Status iframe of the website widget has a huge transparent body element which prevents all clicks on UI elements behind it.

Example:

The 'Cancel' button is completely visible but impossible to click in this case, because it registers as a click in the Trengo iframe. However it doesn't open the chat when clicked in the blank space, so for the end user our website seems broken.

Because everything is embedded within an iframe, we also cannot modify the CSS to fix this ourselves.

Please fix this!
