Writer doc with database form, no macros

Open the attached text document with a database form. The form does not work
because the data source specification is missing.

1. Click the [Edit] button
2. On toolbar "Form Design" or "Form Controls" turn on design mode (button #2)
3. Get the forms property (button #4), tab "Data"
4. Pick "Bibliography" from the "Data Source" drop down. Notice that the
"Content" property turns blank which is expected behaviour.
5. Choose table "biblio" from the "Content" drop down.
6. Save the document. 
7. Reload the document.
Result: Form document opens in read-only mode with data in the form grid.

Now repeat steps 1. to 3.
4. Click the [...] button near the "Data Source" box instead of picking the
registered name. Browse to your user profile, subfolder "database" and pick
biblio.odb
Repeat steps 5. to 7 (Content="biblio", save, reload)
Result: Form document opens in read-only mode with NO data in the form grid.

Repeat steps 1. to 3. The "Data Source" property is blank.

I found this with LibreOffice 5.3.4.2 on Linux.
LibreOffice 5.2.3.3 on Windows(x64) does not show this problem.</pre>
