Describe the bug
When I add properties to any shape, after a few minutes, the properties disappear and the text in the shape itself also disappears.

To Reproduce
Steps to reproduce the behavior:

1. Go to any shape
2. Right-Click on shape
3. Select Edit Data
4. Add properties
5. Click "Apply"
6. Wait a few minutes, and shape text and data properties disappear.

Expected behavior
I expect for the properties to save and for the text in a shape to not disappear

Additional context
Add any other context about the problem here.

Start by reproducing the issue in draw.io v29.3.7 using Chrome on macOS: open a shape's Edit Data dialog, add properties, apply them, and wait for the text and properties to disappear. Trace the shape data editing and saving behavior; done means both the shape text and added properties remain after waiting and saving.
