"False alarm" after hibernation wake-up: Doxument could not be loaded, lost connection

[svenb1234]

Describe the bug
Although the latest version is loaded, the editor claims that the document could not be loaded and the connection is lost.

To Reproduce

1. Open a text document with some content in the browser and hibernate the computer
2. Use a different device to add some text to the document
3. Start the hibernated computer again and watch the browser window
4. At first nothing happens, no notification of a lost connection or alike
5. Then the document is automatically updated, i.e. the text added on the second device appears
6. But at the same time the notification at the bottom of the screen appears. that the connection was lost and the document could not be loaded.

Expected behavior
If the document can be loaded/updated, do not show that error message or "remove" it, cancel it as soon as the connection is re-established.
