Create a new note. Open it to the right as well. Use source mode in the left split and reading mode in the right split. Now, in left split, add ‘topics’ property but keep it empty. Add any content to the note. Now in the reading view, add a topic in ‘topics’ property. The content vanishes.
The topic should be added whilst keeping everything else intact.
Actual result
The content of the file are deleted.

Additional information
Video demonstrating the behavior in a sandbox vault.
I’ve experienced the same problem. It seems as if the contents of the file jumps back to a previous state. I did also first add properties in source mode, then when adding a new property via the GUI in reading view as soon as I’ve given the name to the new property and tabbed away from the field, the content jumps back to a previous state reflecting quite a while back in time (minutes).
It looks as if the YAML code is reformatted as soon as you add a property via the GUI. Does that have anything to do with it?
