Chrome: Cross-origin plugin content from must have a visible size larger than 400 x 300 pixels

I am using Google Chrome Version 62.0.3202.94 and recently get this new error message in the developer console:

Cross-origin plugin content from must have a visible size larger than 400 x 300 pixels, or it will be blocked. Invisible content is always blocked.

Site: https://www.matheretter.de

Clicking on the error brings me to the first line of the HTML: <!DOCTYPE html> which is not helpful to track down the problem.

Can anyone help?

That is likely Flash content being blocked (check the console, it will likely report a URL with an swf file). Google started de-emphasizing Flash over a year ago. According to the article and forum thread below, Chrome actually started "pausing any cross-origin plugin content smaller than 400px in width or 300px in height" in September 2015, now I suppose it's blocking it altogether:
