Proactive message not hiding / closing automatically

❓CSS / React chat❓Webchat

Hello, since Friday on all chatbots I have been experiencing issues with the proactive message, which does not hide/close automatically, even though the widget is in opened state. User must close it manually. Is this a bug, or maybe some conflict with css styling?

Here is example client website: https://www.khk.cz/

Here is the corresponding .css stylesheet file used for this widget: https://hypedigitaly.github.io/KHK/styles/style.css
