After macOS waking up without internet connection, no website is shown

Describe the bug

I'm working on different setups where one has internet through WLAN and the other over LAN. When switching workplaces (opening/closing the lid) it seems Plash can not reload the web page or get back to the last state.

To reproduce

Steps to reproduce the behavior:

1. Open any website
2. Turn off w-lan
3. Close the lid
4. Open the lid
5. red Plash icon
6. no website

Expected behavior

Saving the last state and waiting for a new internet connection or use a service worker to save the site offline.

Info

• macOS version: 10.15.2
• Plash version: latest (don't know where I can see this, mabye add the version and hash as read only menu item)
